Explicitly correlated Gaussian functions and nonlinear optimization techniques have been used to calculate Born-Oppenheimer energies of the ground states of H~-and Hell Γ· ions and several excited states of the hydrogen molecule at equilibrium nuclear configurations. In all the cases the results are

## Abstract The difference in the electron correlation between H^‐^ and other two‐electron atoms is clarified by the introduction of the __r__~12~ term in the wave function. By using the expansion of __r__~12~, a certain modification of the usual electron correlation factor 1 + __Cr__~12~ is introd
