Gamow Shell Model Description of \(^7\)Li and Elastic Scattering Reaction \(^4\)He(\(^3\)H,\(^3\)H)\(^4\)He

Abstract

Spectrum of $^7$Li and elastic scattering reaction $^4$He($^3$H, $^3$H)$^4$He are studied using the unified description of the Gamow shell model in the coupled-channel formulation (GSMCC). The reaction channels are constructed using the cluster expansion with the two mass partitions [$^4$He + $^3$H], [$^6$Li + n].
