Production of heavy and superheavy nuclei in massive fusion reactions

Within the framework of a dinuclear system (DNS) model, the evaporation-residue excitation functions and the quasi-fission mass yields in the 48Ca induced fusion reactions are investigated systematically and compared with available experimental data. Maximal production cross sections of superheavy nuclei based on stable actinide targets are obtained. Isotopic trends in the production of the superheavy elements Z = 110, 112–118 based on the actinide isotopic targets are analyzed systematically. Optimal evaporation channels and combinations as well as the corresponding excitation energies are proposed. The possible factors that influencing the isotopic dependence of the production cross sections are analyzed. The formation of the superheavy nuclei based on the isotopes U with different projectiles are also investigated and calculated.

A BGO detector array and its application in intermediate energy heavy ion experiments

A BGO crystal (Bi4Ge3O12) as the E detector of ΔE-E for identification of reaction products has been used for detecting the charged particles emitting from the 25 MeV/u 40Ar induced reaction. The responses of the BGO crystal to various light charged particles were measured. A close-packed hexagonal array consisting of thirteen ΔE-E telescopes (Si-BGO) has been developed to detect the light charged particles interfering with each other in intermediate-energy heavy-ion induced reactions. Some applications of this telescope array are also described.
