## Abstract The behavior of the electron density __n__(__r__) and potential energy __V__(__r__) near the origin, where an impurity of charge __Z__ is located, is studied using the Lindhard dielectric theory of the freeβelectron gas. The leading odd terms in the powerβseries expansion of __n__(__r__
