Contribution

It applies the Statistical Multifragmentation Model to classify mass yield characteristics over a broad energy range, linking theoretical predictions with experimental trends.

Findings

Mass distributions vary systematically with excitation energy.

Results align with experimental data for heavy nuclei.

The model captures the transition from fission to evaporation regimes.

Abstract

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) up to higher energies about 12 MeV/n, we classified the mass yield characteristics for heavy nuclei (A>200) on the basis of Statistical Multifragmentation Model. The evaluation of fragment distribution with the excitation energy show that the present results exhibit the same trend as the experimental ones.
