Abstract
Calculations are presented of the equilibrium configuration ("dimple") of a Na2 or Li2 molecule absorbed on the surface of liquid3H e or liquid4He. The computed aimer binding energies are somewhat greater than those of the monomers. The lowest energy occurs when the molecule lies flat, but the energy in the erect orientation is only ∼ 1K higher (implying relatively free rotation). The center of mass lies ∼ 4Åabove the liquid surface and the dimple has a depth ∼ 3Å. An exceptional case is Li2 on liquid3H e, for which the surface state is unstable relative to solvation in the bulk.
