Abstract
Energy spectra have been measured for helium and hydrogen isotopes emi tted from highly excited residues produced in central Xe-129 + Cu-nat collisions at E/A = 30 MeV. The observed differences between the spect ra for He-3 and He-4 nuclei can be attributed to the time dependent ev aporative cooling of the residues. This cooling dynamics is also refle cted in a characteristic dependence of isotope ratios on the kinetic e nergy of the emitted particles in reasonable agreement with present ev aporative models.
