2014 A parameter-free semiquantal approach is used to calculate the density and energy in the boundstate Coulomb problem. Unlike most semiclassical methods in current use, our approach dispenses with the energy density functional. The self-consistent application of the method to the atomic problem is illustrated by a numerical example. J. Physique LETTRES… (More)
