This paper presents the results of calculations of spectroscopic parameters of three-particle quantum systems, in particular the exotic helium atom (3He2+,e,³H̅̅). These calculations were made within the framework of a nonrelativistic quantum-mechanical model for the problem of three bodies interacting according to the Coulomb's law.
