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.
