Query: A Statistical Approach to Describe Highly Excited Heavy and Superheavy
  Nuclei   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 $\gamma$-ray, light particles (neutrons,
protons, $\alpha$ etc) in competition with the 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
$^{28}$Si+$^{198}$Pt reaction can be reproduced nicely well within the
approach.
