Calculation of direct-semidirect radiative proton capture with Skyrme-Hartree-Fock-BCS model

Abstract

We calculate the direct-semidirect (DSD) radiative proton capture cross section on 112Sn, 63Cu, and 209Bi in the microscopic Hartree-Fock-BCS approach using the Skyrme interaction. Compared to the compound process, the DSD process becomes dominant in the proton capture reaction above ten and several MeV incident proton energies. We compare several particle-vibration coupling forms, which is sensitive to the semidirect cross section.
