回顾了晕核发现以来双中子集团结构的研究进展，分析了可能的发展方向。系统的理论研究表明， 在原子核的表面和低密度核物质中， 空间紧密关联的2n集团的出现是一个普遍的现象。 但在较重原子核表面出现2n集团的机制与核物质或轻晕核中的机制很不一样， 前者是由有限核的平均场造成的尺度效应（size effect），而后者主要是由低密度下对相互作用（或对能隙）的增强造成的。另外，在轻晕核或有限核表面，2n集团的均方根半径与它们到核芯的距离（或背景密度）有关，最小值普遍可以达到2～3 fm，然而在核物质中2n集团最小只能到～5 fm。 实验方面，在重靶上的库仑激发强度， 能够比较准确地给出2n系统到核芯的平均距离。 但到目前为止尚没有有效的实验方法给出基态中两个中子之间的间距， 主要原因是中子发射过程中末态相互作用（共振态或虚粒子态）造成的两步过程的干扰， 这个问题在库仑激发破碎（重靶）或核作用破碎（轻靶）中都出现。“拖出”反应和敲出核芯反应是下一步可以考虑的路径。 双中子的关联测量通常效率比较低，尤其是需要有效排除中子串扰(CT)事件。为此， 需要发展特殊设计的中子关联测量装置， 在提高探测效率的同时，能够通过运动学关系以及其他方法有效排除中子CT信号。 在数据处理阶段，通过反复迭代给出的双中子关联函数， 经验证明是比较有效的关联状态表达方式， 从中可以直接提取出双中子分布均方根半径。 This article outlines the progress in the study of the dineutron structure in various systems. Systematic theoretical investigations reveal that dineutron structure is a general phenomenon appeared at nucleus surface and in low density nuclear matter. But the underline mechanism of forming dineutron clusters at the surface of heavier nuclei is quite different to that for light halo nuclei or at the low density nuclear matter， with the former being basically due to the so called “size effect” and the latter due to the enhanced pairing interaction. It is also realized that the RMS radii of the dineutron cluster at the surface of light halo nuclei or heavier finite nuclei varies with the distance from the center of nuclei (or background density) and may attain a minimum of about 2～3 fm， whereas that in the low density nuclear matter may only attain about 5 fm. From experimental side， Coulomb excitation caused by heavy targets provides a good way to extract the mean distance from the center of the neutron pair to the center of nucleus. But up to now it is still difficult to experimentally determine the distance between the two valence neutrons， due primarily to the final state interactions which lead to two step emission of neutrons via resonances or virtual intermediate states. This problem happens in both Coulomb and nuclear breakup processes. Possible ways to avoid this problem might come from experiments based on “towing mode” or core knockout reactions. Detection of two neutrons in coincidence often suffers from low efficiencies and the need to reject the cross talk events. Therefore it is important to develop specially designed multineutron detection array to achieve high efficiency as well as good cross talk rejection performance using kinematics conditions. For data analysis， it was found that two neutron correlation function generated by iteration method is a good expression of the correlation situation， from which the RMS radii of the two neutron distribution may be deduced.
核反应截面替代测量方法是一种间接测定核反应截面的方法， 这种方法对于测定不稳定核的反应截面具有重要的意义。 详细介绍了替代方法的理论基础、 影响其精确性的重要因素， 以及基于该方法的3种变型方法： 外替代比率方法（ESRM）、 内替代比率方法（ISRM）和混合替代比率方法（HSRM）。 阐明了每一种方法的基本原理， 给出了相关的实验验证， 并且对每一种方法的优缺点进行了分析。发现在每一种方法中， 所求反应与替代反应之间的自旋宇称不匹配始终是不可消除的一个影响因素。 但是经过实验验证， 替代方法（包括3种变型方法）也可以达到较高的精确度， 因而在不能够直接测定核反应截面的情况下， 该方法不失为一种很好的间接测量方法。The surrogate nuclear reaction approach plays an important role in the determination of nuclear reaction cross sections that are difficult to be measured directly. In this paper， we investigate its basis， factors affecting its accuracy， and its three variants: the external surrogate ratio method (ESRM)， the internal surrogate ratio method (ISRM) and the hybrid surrogate ratio method (HSRM). Each method was described， and their applications or experimental tests were given， from which we could see their respective advantages and disadvantages. And it is found that the spinparity mismatch， or the (weak) WeisskopfEwing limit equivalently， is an inherent limitation of the approach. It is also seen that the surrogate approach can reach a high accuracy， so it is a good indirect approach when the nuclear reaction cross sections are unavailable to be measured directly.
计算了pp和pÞ碰撞中J/ψ的领头阶光生过程的产额。运用非相对论量子色动力学回顾了重夸克偶素产生的色单态机制与色八重态机制，并将它们分别用于处理直接光子过程和分解光子过程。通过与J/ψ产生的领头阶结果的对比可以看出，光生过程对J/ψ产额的修正在大横动量区域变得明显。The production of J/ψ originating from photoproduction processes in pp and pÞ collisions at leading order is calculated. The color singlet and color octet mechanisms for heavy quarkonium production are reviewed within nonrelativistic QCD, and be used to deal with the direct photon and resolved photon processes respectively. Comparing with the leading order results of J/ψ production, the numerical results show that the modification of photoproduction processes for J/ψ production become obvious at large p-T region.
基于推广的QCD向量介子为主的模型（QCD-VMD）和具有QCD特征的程函近似， 研究了光子-光子的相互作用。与通常用费曼盒子图计算光子-光子的相互作用不同， 采用QCD理论揭示了光子-光子的相互作用过程， 认为光子-光子的弹性散射是通过两个散射的光子所涨落成的两个夸克反夸克对之间的强相互作用而进行的。 由于强相互作用的传播子是带色的胶子和胶子的自相互作用的性质， 交换的胶子可以形成无色的胶子球， 无色的张量胶子球（两个雷其化的胶子束缚态）和Odderon(三个雷其化的胶子束缚态)， 可以是两个夸克反夸克对之间的作用的媒介子， 这个机制非常不同于其他理论描述， 特别是考虑了由虚胶子（束缚夸克和反夸克形成的涨落介子）的贡献。 计算了总截面σtot， 微分截面dσ/dt， 向前散射振幅实部与虚部的比率ρ和γγ弹性散射的核斜率参数函数β。在实验误差的范围内， 对总截面σtot的理论预言和实验数据是一致的， 但急需dσ/dt，ρ和β的实验数据来检验本理论模型。Based on the generalized QCD vector meson dominance model and the QCD Inspired Eikonalized approximation, γγ interaction has been studied in this paper. Unlike the usual calculations of the γγ interaction by the Feynman box diagram technique, we explore the process by QCD theory in which γγ elastic scattering proceeds through a strong interaction between two pairs of quarkantiquark fluctuated by two scattering photons. Due to the fact that the mediator of strong interaction is colorful gluon，and gluon has a property of self-interaction which can bind exchanging gluons together to form glueballs. The colorless tensor glueball (two Reggeized gluon bound state) and Odderon (three Reggeized gluon bound state) could be the mediators of the interaction between the two quarkantiquark pairs. This mechanism is very different from the other theoretical descriptions of the process. In particular, the contributions from virtual gluon, bound quarkantiquark to form a fluctuated meson, are taken into account. We calculate the total cross section σtot, the differential cross section dσ/dt, the ratio of the real part to the imaginary part of the forward scattering amplitude ρ, and the nuclear slope parameter function β of γγ elastic scattering. Our theoretical predictions for σtot are consistent with the experimental data within error bars of the data. The data for dσ/dt, ρ and β are urgently needed to test our theoretical model.

基于HIRFL-CSR肿瘤重离子治疗终端主动式束流配送系统发展了面向三维点扫描适形调强治疗技术的在线监测器点扫描剂量标定方法。为了验证点扫描剂量标定方法的稳定性和可靠性，利用HIRFL-CSR提供的C离子束考察了在线监测器剂量标定因子的能量依赖以及不同扫描步长的影响。结果表明：在线监测器剂量标定因子存在能量依赖；不同扫描步长对剂量标定因子影响较小（偏差小于1.8%）。证明了点扫描剂量标定方法的稳定性和可靠性。鉴于在三维点扫描适形调强治疗技术中影响在线监测器点扫描剂量标定因子的因素较多，建议今后续继续研究点扫描剂量标定因子影响因素，修正和完善点扫描剂量标定方法。As an important step of the application of spot scanning technique to heavy ion therapy， an experimental calibration procedure of online beam monitors based on standard of absorbed dose to water has recently been developed for scanned pencillike carbon ion beam in the deep seated tumor therapy terminal at the Heavy Ion Research Facility in Lanzhou (HIRFL). In this work， creating homogeneous irradiation field with steerable spot beam was tested using a 207 MeV/u penci like carbon ion beam. Then the verification of energy dependence of the calibration factors (CFs) and the influence of scanning step on the CF were also shown， as a part of the heavy ion clinic dosimetry researches. The results showd that the monitor CF presented energy dependence and performed stable response with deviation of 1.8% for the variation of scan steps. In this paper， the suitability and effectiveness of beam monitor calibration procedure for dynamic particle beam delivery were verified and the further research points to improve the calibration procedure were suggested.
在室温下，将能量为80 keV， 注量分别为1×1016和1×1017ions/cm2的Co+离子注入到10 mm×10 mm×0.5 mm的单晶TiO2样品。在氮气保护下， Co+离子注量为1×1017 ions/cm2时样品在温度为900 ℃的条件下退火30 min。 利用超导量子干涉仪 （SQUID）测量样品磁性， 并应用X射线衍射（XRD）和扩展边X射线吸收精细结构谱（EXAFS）研究Co+离子注入后样品的微观结构。 样品磁性测量结果表明：Co+离子注入后的样品具有室温铁磁性， 并且其饱和磁化强度的大小与Co+离子注量及样品是否经退火处理有关。 EXAFS研究表明： Co元素在Co+离子注量为1×1017ions/cm2的样品中主要以团簇形式存在；样品经退火处理后， Co团簇消失， 并发现Co部分替代TiO2单晶中的Ti。Co+离子注入后， 在样品中形成Co团簇与否受离子注量的影响。 阐述了样品微观结构与铁磁性来源之间的关系。 At room temperature， monocrystalline plates of rutile (TiO2) were implanted with cobalt ions of an energy of 80 keV to fluences of 1×1016 and 1×1017 ions/cm2 respectively . The 1×1017 ions/cm2 Co implanted samples were annealed in nitrogen at 900 ℃ for 30 min. The magnetic properties of Co implanted samples were measured with a superconducting quantum interference device magnetometer (SQUID) at room temperature. Furthermore, the X ray diffraction (XRD) and Extended X ray Absorption Fine Structure (EXAFS) were applied to investigate the structural and compositional properties of Co implanted samples. The magnetic measurements of samples showed that the size of the saturation magnetization of the Co implanted samples were related to the fluence of ions, and the saturation magnetization of the sample after annealed decreased significantly. The EXAFS measurements showed the presence of cobalt metallic clusters in the sample implanted to ion fluence of 1×1017 ions/cm2. The Co metallic clusters disappeared in the sample after annealed, and resulted in the oxidized Co, which is presumed to substitute into the Ti site. The formation of Co clusters or not was determined by the ion fluence. The relation between ferromagnetic behavior and microscopic structure of the Co implanted samples is discussed.
利用Geant4蒙特卡洛程序包， 基于RPP (Rectangular ParallelePiped Volume)模型构建SRAM器件单元的灵敏体积， 编写了重离子在器件材料中的输运程序和单粒子翻转截面计算方法， 得到了简化器件结构的单粒子翻转截面σ与线性能量转移LET的关系曲线， 计算得到的翻转LET阈值和饱和截面与实验结果基本一致。模拟获得了LET值为99.69 MeV/(cm-2·mg)的Bi离子及LET值为69 MeV/(cm-2·mg)的Bi离子和Xe离子在器件材料中产生的δ电子分布图像，讨论了δ电子分布对翻转截面的影响。 计算了灵敏体积中能量沉积与δ电子分布的关系，认为δ电子分布对单粒子效应的影响随着器件的特征尺寸减小将更加严重。In this paper, the sensitive volume of SRAMs was constructed based on RPP(Rectangular ParallelePiped Volume) model using the Monte-Carlo code Geant4. The interactions of heavy ion with materials and the SEU(Single Event Upset) cross section calculation method were presented in the program. The SEU crosssection curves with the linear energy deposition ware obtained. The SEU threshold value and saturation cross section were consistent with the testing data with heavy ions beam. The δ electrons distribution were different in the device material, which were generated by Bi ion with LETs of 99.67 MeV/(cm2·mg) and Bi ion, Xe ion with LETs of 69 MeV/(cm-2·mg). These results indicate δ electrons distribution impacts on the SEU cross section. According to the relation of energy deposition in the sensitive volume, the δ electrons distribution have more and more important effect on the Single Event Effect with reducing the feature size of semiconductor devices.
研究了平行玻璃板对高流强（约80 nA）105 keV Ar7+离子的导向效应， 利用一维位置灵敏探测器测量了不同倾斜角下出射离子的强度及角分布。 实验结果表明， 平行玻璃板对Ar7+离子有导向作用。 与离子在微孔膜中的导向效应不同， 从平行玻璃板出射的Ar离子角分布的FWHM随着倾斜角的改变而改变， 并且出射离子角分布最大值处对应的观察角不等于倾斜角。 The transmission of 105 keV Ar7+ ions with high incident current (about 80 nA) through the gap formed by a paired parallel glass plates was investigated. The intensity and angular distribution of the transmitted ions for various tilt angles were measured using a onedimensional position sensitive detector. The results indicate the existence of a guiding effect when Ar7+ ions pass through the gap， but it is different from that for ions passing through nonacapillaries. We found a measurable dependence of the full width at half maximum (FWHM) of the transmitted ions as a function of the tilt angle. In addition， when the gap was tilted with respect to the direction of the incident beam， the observation angle related to the center of the transmitted ions profile was not equal to the tilt angle.
