Abstract Accurate mass-interpolation and mass-asymptotic formulas are derived for one- and two-center three-body ions with unit charges. The derived formulas are applied to predict accurate numerical values of the total energies of the ground (bound) 1 1 S ( L = 0 ) - states in one-center atomic ions X + e - e - and analogous ground (bound) 1 s σ - states in the two-center, quasi-adiabatic (or quasi-molecular) X + X + e - ions. We also discuss a few problems which currently remain unsolved for… Expand
