Query: Description of the proton and neutron radiative capture reactions in the
  Gamow shell model   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,gamma)8B and
7Li(n,gamma)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- and the
first excited state 1/2- of 7Be/7Li and the proton/neutron wave function
expanded in different partial waves.
