The Bethe-Goldstone equation is replaced by a rigorous nonlinear integro- differential equation determining the two particle correlations and the interaction energy. This nonlinear equation is solved for vanishing total momentum and separable potential. The hole-hole and particle-hole interactions as well as the three- and four-particle clusters are neglected. There are no singularities in this more rigorous equation. For the values of the two-particle energy for which singularities occur, if the quadratic terms are neglected, the solutions are of "compound type," i.e., the localized part has a large (but finite) amplitude compared with the unperturbed plane wave.
