Abstract
The large-N collective field formalism developed by Jevicki and Sakita is applied to the many electron system around a large-Z nucleus. It is shown that the well known energy level of the hydrogenlike atom can be reproduced as the excitation spectrum of the charge density vibration. The structure of atomic electron system with short-range repulsive interaction is investigated within the high-density approximation.
