Abstract

We summarize a description of heavy-ion fragmentation reactions at low and intermediate energies in terms of a Boltzmann-Vlasov transport approach for the production of the hot, excited primary fragments, followed by a statistical decay of these to arrive at the measured cold fragments. We compare isotope distributions and velocity spectra to experimental data. While the isotopic distributions are reasonably well-described by this microscopic approach, there are larger differences in the velocity distributions. These seem to be due to too small fluctuations in the transport calculation and to the presence of more direct reaction processes in the data.
