Abstract
Presents a new method of calculating the dispersion force between two atoms. This force has usually been calculated by expanding the electric interaction into the interaction between the multipole moments; this method, however, has the defect of giving a divergent series for the dispersion force. The new method gives a convergent series which is expressed in terms of physical properties of the separated atoms and which approaches a well known inverse-power series as the nuclear distance goes to infinity. The method is applied to hydrogen atoms.
