摘要: The influence of correlations on the critical temperature and density for onset superfluidity in nuclear matter is investigated within scheme Nozieres Schmitt-Rink [1]. For symmetric a smooth transition from Bose-Einstein condensation (BEC) deuteronlike bound states at low densities temperatures to Bardeen-Cooper-Schrieffer (BCS) pairing higher described. Compared with mean field approach lowering obtained as well pure neutron matter. Mott discussed. Regions temperature-density plane are identified where correlated pairs give main contribution composition system, so that approximations beyond quasi-particle picture requested.
