Abstract

We present the results of a multifragmentation model incorporating a primordial fragment distribution based on statistical multifragmentation followed by sequential decay of the resulting fragments. The Coulomb trajectories of the fragments are followed. The size of the emitting system and the excitation energy are chosen to reproduce the first order observables of the experimental results for 35 to 85 MeV / nucleon Ar+V collisions measured with the MSU 4Π Array. Event-shape analysis in terms of sphericity-coplanarity is carried out and demonstrates that multifragmentation occurs in this system for all energies above 45 MeV / nucleon.
