摘要：

We report "exact" ab initio calculations with reduced statistical error for the potential energy of interaction of two helium atoms. For the equilibrium internuclear distance of 5.6 bohr, the calculated electronic energy is -5.807 483 53+/-0.000 000 06 hartrees and the corresponding well depth is (epsilon /k) 10.98+/-0.02 K.
