Correlations between energy and mass partition in the damped reactionHo165+74Ge atElab=8.5 MeV/nucleon

Data from a kinematical coincidence experiment on the damped reaction ${}_{}{}^{165}{}_{}{}^{}\mathrm{Ho}$ ${+}^{74}$Ge at 8.5 MeV/nucleon have been reanalyzed. Although the new analysis confirms the presence of some correlations between the excitation-energy division and the mass asymmetry, the magnitude of these correlations is found to be significantly smaller than that previously reported. Proton-neutron symmetry of the mechanism of heat generation through nucleon exchange is revealed and a possible acceptor-donor asymmetry of this mechanism is discussed.
