Abstract
Deeply inelastic heavy-ion collisions from 14 to 25 MeV/u are investigated within a microscopic transport approach of the VUU type where the time-dependent mean field and the in-medium cross section are based on the same parametrization of the G-matrix. The transfer of energy and angular momentum from the relative motion to the internal degrees of freedom is studied in detail as a function of impact parameter and found to be dominated by nucleon exchange. The fluctuation in mass, furthermore, can also be ascribed to the random nucleon transfer mechanism. We calculate double-differential spectra with respect to total kinetic energy loss (TKEL) and mass as well as with respect to TKEL and scattering angle. Furthermore, the exclusive production of hard photons in Mo + Mo reactions at 19.5 MeV/u is found to be well described by incoherent proton-neutron bremsstrahlung as evaluated from the same parametrization of the G-matrix.
