    "abstract": "Finite nuclei such as those found in the chain of even tin isotopes from\n^{102}Sn to ^{130}Sn, exhibit a near constancy of the 2^+_1-0^+_1 excitation\nenergy, a constancy which can be related to strong pairing correlations and the\nnear degeneracy in energy of the relevant single particle orbits. Large\nshell-model calculations for these isotopes reveal that the major contribution\nto pairing correlations in the tin isotopes stems from the ^1S_0 partial wave\nin the nucleon-nucleon interaction. Omitting this partial wave and the ^3P_2\nwave in the construction of an effective interaction, results in a spectrum\nwhich has essentially no correspondence with experiment. These partial wave are\nalso of importance for infinite neutron matter and nuclear matter and give the\nlargest contribution to the pairing interaction and energy gap in neutron star\nmatter.",
