Abstract
The lowest-order relativistic correction to the helium-helium interaction energy has been calculated for the first time, using two independent methods based on expansions in explicitly correlated Gaussian functions. At the equilibrium interatomic distance of 5.6 bohr, this correction amounts to +15.4±0.6mK. As a by-product, a new upper bound of -10.9985K for the nonrelativistic Born-Oppenheimer interaction energy has been obtained. © 2005 The American Physical Society.
