Spectroscopic Parameters of the Exotic Helium Atom within the Hyperspheric Adiabatic Approach in One-Dimensional Space

This paper presents the results of calculations of spectroscopic parameters of three-particle quantum systems, in particular the exotic helium atom (He-3(2+), e, (H-3) over bar). 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.
