Title: Unitary and Separable Approximations to the Two-Particle Transition Amplitude
Abstract: Unitary and separable approximations to the two-particle transition amplitude are constructed in such a way that the region of good agreement with the exact amplitude can be chosen with some freedom. We discuss the origin of non-physical poles in such approximations and indicate how they can be avoided.
