Neutron-proton pairing correlations in a single l−shell model

Abstract

The long standing problem of neutron-proton pairing correlations is revisited by employing the Hartree-Fock-Bogoliubov formalism with neutronproton mixing in both the particle-hole and particle-hole channels. We compare numerical calculations performed within this method with an exact pairing model based on the SO(8) algebra. The neutron-proton mixing is included in our calculations by performing rotations in the isospin space using the isocranking technique.
