The binding of 4He and 3He to a hydrogen molecule: a computational study for pH2 and oH2.
One bound state for the very weakly interacting complex of H(2) with one He atom is computed using a recently obtained, very accurate potential energy surface [A. I. Boothroyd and P. G. Martin, J. Chem. Phys. 119, 3187 (2003)] and employing a discrete variable representation expansion. The spatial features of this very diffused, "halo" state are analyzed and discussed for various isotopic variants of the title system.
