Stimulated by the still puzzling competition between spin-singlet and spin-triplet pairing in nuclei, the $^{3}SD_{1}$ neutron-proton pairing is investigated in the framework of BCS theory of nuclear matter. The medium-polarization effects are included in the single-particle spectrum and also in the pairing interaction starting from the $G$ matrix, calculated in …
