Cluster Model for Near-barrier Fusion Induced by Weakly Bound and Halo Nuclei

TL;DR

This paper investigates how coupling transfer and breakup channels affect near-barrier fusion in systems involving weakly bound and halo nuclei, using the CDCC model, with applications to $^{6}$He+$^{59}$Co.

Contribution

It introduces a detailed analysis of coupling effects on fusion involving halo nuclei using the CDCC approach, extending understanding to $^{6}$He induced reactions.

Findings

Coupling effects significantly influence fusion cross sections.

The CDCC model effectively predicts fusion behavior near the Coulomb barrier.

Applications to halo nuclei demonstrate unique fusion characteristics.

Abstract

The influence on the fusion process of coupling transfer/breakup channels is investigated for the medium weight $^{6,7}$Li+$^{59}$Co systems in the vicinity of the Coulomb barrier. Coupling effects are discussed within a comparison of predictions of the Continuum Discretized Coupled-Channels model. Applications to $^{6}$He+$^{59}$Co induced by the borromean halo nucleus $^{6}$He are also proposed.
