摘要：

The role of system size and momentum dependent effects are analyzed in multifragmenation by simulating symmetric reactions of Ca + Ca, Ni + Ni, Nb + Nb, Xe + Xe, Er + Er, Au + Au, and U + 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.
