Abstract

We formulate the Gamow shell model (GSM) in coupled-channel (CC) representation for the description of proton/neutron radiative capture reactions and present the first application of this new formalism for the calculation of cross sections in mirror reactions ⁷Be(p,\ensuremathγ)⁸B and ⁷Li(n,\ensuremathγ)⁸Li. The GSM-CC formalism is applied to a translationally invariant Hamiltonian with an effective finite-range two-body interaction. Reactions channels are built by GSM wave functions for the ground state 3/2^\ensuremath- and the first excited state 1/2^\ensuremath- of ⁷Be/⁷Li and the proton/neutron wave function expanded in different partial waves.
