The study of fusion barriers of neutron-rich colliding nuclei using various isospin-dependent potentials

TL;DR

This paper investigates fusion barriers in neutron-rich nuclei using isospin-dependent potentials, revealing systematic trends in barrier positions and heights that align well with existing data.

Contribution

It introduces a unified nonlinear parametrization for fusion barrier positions and heights based on N/Z ratio, enhancing understanding of neutron-rich nuclear fusion.

Findings

Fusion barrier positions increase monotonically with N/Z ratio.

Fusion barrier heights decrease monotonically with N/Z ratio.

The parametrization aligns well with theoretical and experimental results.

Abstract

A detailed study fusion of neutron-rich colliding nuclei is performed using various isospin dependent potentials. For present study, Three different series namely, Ne-Ne, Ca-Ca, and Zr-Zr are taken into account and N/Z ratio.A monotonous increase (decrease) in the fusion barrier positions (heights) using a unified second order nonlinear parametrization in the normalized fusion barrier positions and heights with (N/Z-1) is presented. These predications are in good agreement with the available theoretical as well as experimental results.
