Abstract:
The new neutron-rich isotope 208Hg was identified for the first time from the reactionproducts in a thick natPb target bombarded by a 30MeV/u 12C beam. The identification of 208Hg wasbased on two-step chemical separation and γ activity analysis. The first step was the release,separation and collection of Hg element products with a high efficiency and good selectivity bymeans of a melt target device and a special thermochromatographic technique developed in presentwork. The second step was..

Abstract:
The history and status of transuranium nuclei synthesis is described. Feasibleprojectile target combined to produce new neutron-deficient trasuranium nuclei is proposed.Production cross section is estimated and fission competition is corrected. Experimental set upincludes He-jet transport system and rotating wheel collection system. Mother-daughter detectorsystem can be used to identify unknown nuclei by genetic relation between mother and daughternuclei.

Abstract:
The average formation cross sections of the targetlike residuals produced in theinteractions of 47MeV/u ~(12)C with ~(133)Cs、~(209)Bi and ~(197)Au targets were measured by means of theradiochemical separtion and γ-spectroscopy techniques. The mass-yield curves of I、Hg、Au、Ptisotopes were obtained. It is found that the mass difference between the target nucleus and the mostprobable products for the targetlike isotopes is about 4~5 mass units, every time the target nucleusreduces a proton...

Abstract:
Unusual antishadowing appeared in K~+-nucleus scattering, which was reconfirmed byBrookhaven experiments in 1988~1991. Almost all of the conventional explanations of this effectat nucleon level are not successful. One has to search for new interpretations at quark level.

Abstract:
In this paper, we analysed the experimental data of reaction cross sections induced byfast neutron on ~(10)B by using the direct nuclear reaction theory and the DWBA method. We obtainedthe results in agreement with experimental data and reported a set of parameters. Furthermore, byusing the set of parameters we have calculated systematically the inelastic integrated cross sectionsand angular distribution of ~(10)B(n, n′) ~(10)B 0.717 MeV excited state for incident neutron energiesfrom 7.54 MeV to 20.0 MeV. ...

Abstract:
Atomic physics information is of great importance to fusion reactor design, whichdefine the accessibility of the ignition regime, plasma burn duration and operational parametricspace of the reactor. We discuss the role of atomic physics in several of the most critical reactordesign areas and specify the required atomic physics information including interaction of plasmaparticles with solid surfaces.
