Role of momentum dependent interactions in nuclear stopping

TL;DR

This study investigates how momentum-dependent interactions influence nuclear stopping in neutron-rich collisions, showing that hard momentum-dependent interactions increase stopping and fragment production correlates with stopping efficiency.

Contribution

It demonstrates the significant role of momentum-dependent interactions, especially hard ones, in nuclear stopping and fragment production in neutron-rich nuclear collisions.

Findings

Hard momentum-dependent interactions increase nuclear stopping.

Fragment production correlates with stopping parameter R.

More stopping observed with HMD compared to SMD.

Abstract

In the present analysis, thousand of events were simulated for the neutron rich reaction of 54Xe131 + 54Xe131, at different impact parameters using hard (HMD) and soft (SMD) momentum dependent equation of state. one can clearly see more stopping in the presence of HMD. Production of LCP's and free particles follows the same trend as stopping parameter R. This simply implies that the fragment production can act as a global indicator for the nuclear stopping.
