We calculate the momentum distribution of nucleons in asymmetric nuclear matter within the framework of the extended BruecknerHartreeFock approximation at zero temperature, use Argonne V18 potential as two nucleons potential. The isospinasymmetry dependence of the nucleon momentum distribution predicted and discussed. It is shown that as the asymmetry increases, the proton momentum distribution become smaller while the neutron one gets higher below their respective Fermi surfaces with respect to their common values in symmetric nuclear matter. The quasiparticle strength at the Fermi momentum also calculated and discussed, we got an improved fulfillment of the Migdal Luttinger theorem and nucleon number conservation.

Based on the parameters of the Middle Energy Beam Transport (MEBT) of the Heavy Ion Therapy Facility in Lanzhou (HITFiL)， which is now under design and construction at the Institute of Modern Physics， Chinese Academy of Sciences (IMPCAS)， a debuncher will be used to reduce the momentum spread for the injection requirement of the synchrotron according to the injection demand of the synchorotron. Both analytical model and tracking simulation with MathCAD are used for the choice of debuncher’s parameters. The conclusion shows that the effective cavity voltage of the debuncher is 102 kV and the minimum finial momentum spread is 2.764×10-4.

A small neutron generator has been developed for meeting the need of well logging in oil fields. The miniature cold cathode Penning ion source and single electrode ion optics system are used in neutron generator. The good performance of the generator has been proved in the laboratory test and well logging in oil field. The generator has good characteristics， such as small diameter， high temperature resistant，high neutron output and good stability. At present， the neutron generator is the smallest logging generator in China， which has been used in oil field generally for conforming the geological data.

p73基因是p53抑癌基因家族的新成员。 p73有两组蛋白异构体: TAp73和DNp73。 TAp73具有诱导细胞周期停滞和细胞凋亡的能力， 而DNp73却有与之相反的能力， 具有肿瘤促进作用。 对p73基因两面性的特点及研究进展作一综述。 最后结合重离子治疗肿瘤， 探讨了p73联合重离子治疗的新思路。 p73 was the first identified homologue of the tumor suppressor gene, p53. p73 has two groups of protein isoforms: TAp73 and DNp73. TAp73 can induce cell cycle arrest, resulting in the ability of apoptosis, however DNp73 has antagonistic property of a tumor promoting effect. In this paper, the dual roles of p73 gene and its research progress was reviewed. Finally, combined with heavy ion treatment of tumor, we explored some new ideas of p73heavy ion joint therapy.
