On the energy of vanishing flow for colliding nuclei leading to same compound nucleus

TL;DR

This paper investigates how the energy of vanishing flow (EVF) in colliding nuclei depends on mass and asymmetry, revealing that EVF increases with asymmetry, especially in lighter nuclei, due to reduced nucleon collisions and Coulomb repulsion.

Contribution

It demonstrates that EVF's dependence on mass asymmetry is independent of the mass, highlighting the role of Coulomb interactions and nucleon collisions in this behavior.

Findings

EVF increases with asymmetry for all nuclei.

The increase in EVF with asymmetry is more pronounced in lighter nuclei.

Mass asymmetry independence of EVF's mass dependence is confirmed.

Abstract

Our present studies has shown that the mass dependence of EVF show mass asymmetry independent behaviour. This is due the fact that with increase in asymmetry, the number of nucleon-nucleon collisions and repulsive Coulomb interactions decreases, therefore EVF increases. The increase in EVF with asymmetry is more for lighter nuclei as compared to heavier nuclei due to the further less magnitude of Coulomb repulsions in lighter nuclei as compared to heavier ones.
