Abstract

The solution to the Schrödinger equation is analyzed for two particles interacting in an external potential. It is assumed that a shallow level exists for one of the particles in the external potential. It is shown that repulsion leads to a transfer of one of the particles to the continuous spectrum after attainment of the interaction threshold. For the shallow level, the threshold value of the interaction is independent of level depth.
