Title: Break-up fragments excitation and the freeze-out volume

Abstract

We investigate, in microcanonical multifragmentation models, the influence of the amount of energy dissipated in break-up fragments excitation on freeze-out volume determination. Assuming a limiting temperature that decreases with nuclear mass, we obtain for the Xe+Sn at 32 MeV/nucleon reaction a freeze-out volume that is almost half the one deduced using a constant limiting temperature.
