Abstract

The binding energies of helium-3 dimer, helium-4 dimer and 3He - 4He molecule in the state 1 1S - 1 1S are calculated using the standard variational procedure. It is shown that the binding energy depends on the retardation long-range potentials. The expectation value of the internuclear distance for each complex is also derived.
