- Gamow Shell Model description of $^7$Li and elastic scattering reaction $^4$He($^3$H, $^3$H)$^4$He Spectrum of ^7Li and elastic scattering reaction ^4He(^3H, ^3H)^4He 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 [^4He + ^3H], [^6Li + n]. 3 authors · Apr 2, 2023
