Abstract
The problem of pairing in semi-infinite nuclear matter is considered i n the Brueckner approach. Equations for effective pairing interaction in semi-infinite matter are derived for the case of the separable repr esentation of realistic NN interaction. The propagator of two noninter acting particles in a semi-infinite potential well is calculated numer ically. The equation for effective interaction is solved for a model d elta-shaped NN interaction, which correctly reproduces NN scattering i n the low-energy limit.
