Fusion systematics for weakly bound nuclei using neutron flow and collective degrees of freedom

TL;DR

This paper systematically analyzes fusion cross sections near the Coulomb barrier for weakly and strongly bound nuclei using neutron flow and coupled channels models, highlighting the influence of collective degrees of freedom and neutron flow.

Contribution

It introduces a combined approach using neutron flow and coupled channels models to explain near barrier fusion data for various nuclei.

Findings

Both models successfully explain near barrier fusion data.

Collective degrees of freedom influence fusion processes.

Neutron flow impacts fusion involving weakly bound nuclei.

Abstract

A systematic analysis of the fusion cross sections around the Coulomb barrier energies with stable weakly bound ($^{6}$Li,$^{7}$Li,$^{9}$Be) and strongly bound $^{12}$C projectiles on various targets was performed by using neutron flow model and coupled channels approach. The analysis show that both the models are successful in explaining the near barrier fusion data. Further, it is also observed that the collective degrees of freedom as well as the neutron flow influence the near barrier fusion process involving weakly bound projectiles.
