Abstract

The potential energy of attraction between hydrogen atoms spaced by distance R on the order of a_B/α, where a_B 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 a_B ≪ R ≪ a_B/α and according to the law of R^–7 at distances R ≫ a_B/α.

氢原子的范德华引力

摘要

距离R 的氢原子之间的吸引力势能约为a _B /α，其中a _B是玻尔半径，α = e ² / \(\hbar \) c = 1/137 是精细结构常数，已确定。根据距离a _B ≪ R ≪ a _B /α处的R ^–6定律，能量取决于R，并根据距离R ≫ a _B /α处的R ^–7定律。
