System size effects and N/Z dependence of balance energy for different isotopic series

TL;DR

This study investigates how the balance energy in nuclear collisions varies with neutron-to-proton ratio across different isotopic series and system sizes, revealing a linear N/Z dependence with system-specific slopes.

Contribution

It provides new insights into the N/Z dependence of balance energy across various isotopic series and system masses, highlighting size-dependent linear behavior.

Findings

Balance energy decreases linearly with N/Z ratio.

Steeper N/Z dependence in lighter systems like Ca+Ca.

Less steep N/Z dependence in heavier systems like Xe+Xe.

Abstract

We study the N/Z dependence of energy of vanishing flow or balance energy for different isotopic series of various system masses like Ca+Ca, Ni+Ni, Zr+Zr, Sn+Sn and Xe+Xe. We find that balance energy decreases with N/Z of the system and follows a linear behaviour. The slope of N/Z dependence is steeper for lighter systems like Ca+Ca and less for heavier ones like Xe+Xe.
