SOME ASPECTS OF THE SCATTERING PROBLEM FOR A SYSTEM OF THREE CHARGED PARTICLES

The question of influence of the spectral neighborhood of an accumulative point of bound energies of a pair subsystem on the structure of eigenfunctions of the continuous spectrum for a system of three charged quantum particles is studied. The unified contribution of pair high-excited states are separated in the coordinate asymptotics of such functions. Bibliography: 20 titles.
UDC 517.9 1. Introduction The diffraction approach in quantum few-body scattering problems was suggested earlier in [1,2] for a system of three one-dimensional neutral quantum particles and later developed in [...]
