摘要：

The neutron-proton superfluidity for nuclear matter in the S-3(1)-3D1 channel is studied within the BCS formalism. In agreement with previous calculations based on the T-matrix approach, a large energy pp is found if one adopts the bare nucleon-nucleon interaction in the gap equation. The dependence of the results on the single-particle spectrum and on the nucleon-nucleon interaction is analyzed and discussed. The relevance of the results for the structure of neutron stars, nuclear matter saturation and superfluidity in finite nuclei is briefly discussed.
