ResumoA light particle is assumed to move in the field of two heavy particles that separate with constant velocity. The resulting field of the two-heavy fragments is approximated by two moving, one-dimensional zero-range potentials. The propagator for this problem is derived in closed form for arbitrary potential strengths. The resulting integral representation is suitable for numerical evaluation.
