Abstract

The potential curve for

{He}_{2}^{+} ({}^{2}Σ_{u}^{+})

has been calculated using Slater-type orbitals as a basis for a 26-term atomic orbital-configuration wave function. The calculation establishes a rigorous lower bound,

E_{\exp} (atoms) - E_{calc} (molecule)

, of 2.24 eV for the dissociation energy of

{He}_{2}^{+} ({}^{2}Σ_{u}^{+})

. This value together with the ionization energies of

{He}^{*} (2 {}^{3}S)

and

{He}_{2}^{*} ({}^{3}Σ_{u}^{+})

is used in an energy cycle to give a lower limit of 1.76 eV for the dissociation energy of

{He}_{2}^{*} ({}^{3}Σ_{u}^{+})
