Influence of Nuclear Charge Radius Parameterization on the Excitation Function of Nuclear Stopping


The initialization effects on the excitation function of nuclear stopping have been depicted through nuclear charge radii parameterizations within the framework of Isospin-dependent Quantum Molecular Dynamics (IQMD) model. The nuclear reactions of 58 58 28 28 Ni Ni + and 124 124 50 50 Sn Sn + have been simulated at incident energies between 30 to 1500 MeV/nucleon for two different nuclear charge radii parameterizations (isospin-independent and -dependent) by including as well as excluding the momentum dependent interactions (MDI). Our study reveals that role of change in radius parameterization on nuclear stopping is more emphasized around 400 MeV/nucleon. MDI affects the nuclear stopping at relatively low energy and its role diminishes with increase in energy. Moreover, the isospin-dependent radius parameterization along with MDI is able to reduce the gap between experimental findings of INDRA and ALADIN collaborations and theoretical calculations.
