摘要：

The widths of the residue-mass distributions are used as a measure of the excitation energy of hot nuclei. They increase with the recoil velocity but saturate much below the calculated velocity vCN for complete fusion. Above these critical excitations energies (4.56.4 MeV/nucleon) derived from the recoil velocity, the normal evaporation of nucleons and small clusters disappears, if a hot and equilibrated compoundlike nucleus is formed at all. © 1990 The American Physical Society.
