英文摘要: A statistical approach based on the Weisskopf evaporation theory has been developed to describe the de excitation process of highly excited heavy and superheavy nuclei, in particular for the proton-rich nuclei. The excited nucleus is cooled by evaporating gamma-rays, light particles (neutrons, protons, alpha etc) in competition with binary fission, in which the structure effects (shell correction, fission barrier, particle separation energy) contribute to the processes. The formation of residual nuclei is evaluated via sequential emission of possible particles above the separation energies. The available data of fusion-evaporation excitation functions in the Si-28+Pt-198 reaction can be reproduced nicely within the approach.
