Abstract
Kinetic energy spectra and fragment velocity correlations, simulated by means of stochastic mean-field calculations, are successfully confronted with experimental data for single multifragmenting sources prepared at the same excitation energy per nucleon in 32 A MeV 129Xe + natSn and 36 A MeV 155Gd + natU central collisions. Relying thus on simulations, average freeze-out times of 200–240 fm/c are estimated. The corresponding spatial distributions of fragments are more compact for the lighter system (∼3–4V0 vs. ∼8V0).
