A systematic calculation for energy deposition in intermediate energy
heavy-ion collisions, concerning the effects of both entrance channel
dynamics and intrinsic properties of nuclei, has been carried out by m
eans of the Boltzmann-Uehling-Uhlenbeck (BUU) simulation. The limitati
on on excitation energy is essentially related to the dynamics of the
entrance channel, while the contribution from the mean field may also
be quite large and cannot be neglected.
