Systematic description of 6Li(n, n')6Li* $\to$ d + $\alpha$ reactions with the microscopic coupled-channels method

TL;DR

This paper uses a microscopic coupled-channels approach with a cluster model to accurately describe neutron-induced reactions and breakup processes in lithium-6, matching experimental data across various energies.

Contribution

It introduces a detailed microscopic coupled-channels method with a cluster model for lithium-6, providing systematic reproduction of elastic and breakup reaction data.

Findings

Good agreement with experimental elastic cross sections between 7.47 and 24.0 MeV

Successful reproduction of neutron spectra to lithium-6 breakup states

Systematic description of reaction mechanisms across energies

Abstract

We investigate $^6$Li($n$, $n'$)$^6$Li$^*$ $\to$ $d$ + $\alpha$ reactions by using the continuum-discretized coupled-channels method with the complex Jeukenne-Lejeune-Mahaux effective nucleon-nucleon interaction. In this study, the $^6$Li nucleus is described as a $d$ + $\alpha$ cluster model. The calculated elastic cross sections for incident energies between 7.47 and 24.0 MeV are good agreement with experimental data. Furthermore, we show the neutron spectra to $^6$Li breakup states measured at selected angular points and incident energies can be also reproduced systematically.
