Study of participant-spectator matter, thermalization and other related phenomena for neutron-rich colliding pair

TL;DR

This study investigates how neutron-richness affects participant-spectator matter, density, temperature, and thermalization in heavy-ion collisions, finding weak dependence on N/Z ratio across various energies.

Contribution

It provides new insights into the weak influence of N/Z ratio on key reaction dynamics in neutron-rich heavy-ion collisions.

Findings

Weak N/Z dependence on participant-spectator matter

Minimal impact of N/Z ratio on density and temperature

Thermalization shows similar weak N/Z dependence

Abstract

We study the participant-spectator matter, density and temperature reached in heavy-ion reactions of neutron-rich systems having N/Z varying from 1.0 to 2.0 at 50 and 250 MeV/nucleon. The N/Z dependence of these quantities is also investigated. Our results show a weak dependence on the N/Z ratio of the system on these quantities. We also shed light on the role of N/Z ratio on the thermalization achieved in a reaction. We find similar weak N/Z dependence on thermalization also.
