Medium mass fragment production due to momentum dependent interactions

Abstract

The role of system size and momentum dependent effects are analyzed in multifragmenation by simulating symmetric reactions of $\mathrm{Ca}+\mathrm{Ca}$, $\mathrm{Ni}+\mathrm{Ni}$, $\mathrm{Nb}+\mathrm{Nb}$, $\mathrm{Xe}+\mathrm{Xe}$, $\mathrm{Er}+\mathrm{Er}$, $\mathrm{Au}+\mathrm{Au}$, and $\mathrm{U}+\mathrm{U}$ at incident energies between 50 MeV/nucleon and 1000 MeV/nucleon and over full impact parameter zones. Our detailed study reveals that there exists a system size dependence when the reaction is simulated with momentum dependent interactions. This dependence exhibits a mass power law behavior.
