Collisions induced by 11 MeV/nucleon 58Ni+24Mg

Measurements of energy spectra for protons, deuterons, tritons, and a particles in coincidence with heavy evaporation residues were made with a large logarithmic detector array which covered the angular range of 3 degrees to 24 degrees. We performed detailed comparisons with statistical calculations which model the evaporative decay of a compound nucleus formed in the collisions. We found out that it was possible to account for the observed energy spectra of the light particles and their relative yields if one assumes initial evaporation from a highly deformed composite system (dinuclear) which at a later stage in the cascade relaxes into a normal compound nucleus.
