By a proper choice of the excitation energy per nucleon we analyze the mass distributions of the nuclear fragmentation at various excitation energies. Starting from low energies (between 0.1 and 1 MeV nucleon- 1) up to higher energies about 12 MeV n- 1, we classified the mass yield characteristics for heavy nuclei (A> 200) on the basis of a statistical multifragmentation model (SMM). The evolution of fragment distribution with the excitation energy show that the present results exhibit the same trend as the experimental ones. © 2007 The Royal Swedish Academy of Sciences.
