Particle evaporation from hot nuclei withA ≦85 mainly prior to scission

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

We report on measurements of fusion-fission fragments and evaporation residues from the reaction58Ni +27Al at 835 MeV incident energy leading to compound nucleiA ≦ 85 with high excitation energies. In the case of fission the mass dependence of the velocity widths of separated fragments indicate that the evaporation of light particles predominantly occurs from the composite nucleus prior to scission. The fraction evaporated from the fully separated fragments after scission can be estimated to approximately 20%.
