摘要：

The self-consistency between a Brueckner like ladder equation for the effective interaction which treats particles and holes symmetrically and the Dyson equation is discussed. A study of pairing instabilities in nuclear matter for realistic nucleon-nucleon interactions is presented. Bound pair states in nuclear matter are obtained and their contribution to the interaction is compared to the continuum contribution using dispersion relations. A survey of simple pairing properties for the Reid potential is made. It is suggested that the actual ground state of nuclear matter around the empirical saturation density corresponds to a superfluid with pairing occurring with deuteron quantum numbers.
