Abstract
The potential energy of attraction between hydrogen atoms spaced by distance R on the order of aB/α, where aB is the Bohr radius and α = e2/\(\hbar \)c = 1/137 is the fine structure constant, has been determined. The energy depends of R according to the law of R–6 at distances aB ≪ R ≪ aB/α and according to the law of R–7 at distances R ≫ aB/α.
