Note on an Approximation Treatment for ManyElectron Systems
Abstract
A perturbation theory is developed for treating a system of n electrons in which the HartreeFock solution appears as the zeroorder approximation. It is shown by this development that the first order correction for the energy and the charge density of the system is zero. The expression for the secondorder correction for the energy greatly simplifies because of the special property of the zeroorder solution. It is pointed out that the development of the higher approximation involves only calculations based on a definite onebody problem.
