For large values of d = 3 N , the radial distribution function of an N ‐particle system is sharply peaked near the hyperradius r m = ( d − 2)/2 k 0 , where k 0 ≡(2/ E /) 1/2 . This fact allows an approximate separation of the hyperradius, leading to many‐dimensional hydrogenlike radial solutions. Kindred applications to dimensional scaling are also discussed, where d = DN , with D the spatial dimension. For the large D regime, illustrative analytic formulas are obtained giving the energy and effective nuclear charge for the lowest few S states of the helium atom.
