In this paper we calculate in atomic unitse — 1,a 0 = 1 and the energyE in units ofe 2/2a0. We adopt these units in order to compare them withHenneberg’s results.
This formula we have obtained using the formula (4), ofJ. Bertrand:Traité de calcul différentiel et de calcul intégral (Paris, 1870), p. 190.
