Astrophysical S -factor for $^{6}$Li(p, γ)$^{7}$Be in the coupled-channel Gamow shell model

Abstract : We have applied the Gamow shell model (GSM) in the coupled-channel representation to study the astrophysical S-factor for the proton radiative capture reaction of 6Li. Reaction channels are built by coupling the proton wave function expanded in different partial waves with the GSM wave functions of the ground state (1+) and the excited states (31+, 01+ and 21+) of 6Li. All relevant E1, M1, and E2 transitions from the initial continuum states in 7Be to the final bound states (3/21− and 1/21−) are included. It is found that the calculated total astrophysical S factor for this reaction agrees well with the experimental data.
