On a new exchange potential

О новом обменном потенциале

Abstract

In the investigation of systems consisting of particles of spin 1/2 by the Hartree-Fock method there occurs the operator of exchange interaction. The semi-classical analogue of this operator is known for various interaction potentials. The purpose of this paper is to present a method which makes possible a more accurate determination of the semi-classical analogue of the exchange operator. The detailed calculations have been carried out for the Coulomb potential.

Резюме

При рассмтрении систем, состоящих из частиц с половинными спинами, методом Гартри—Фока появляется оператор обменного взаимодействия. Полуклассический аналог этого оператора известен в случае различных потенциалов взаимодействия. Целью работы является показать метод, дающий возможность более точно определить полуклассический аналог обменного оператора. Детальный расчет проведен в случае кулоновского потенциала.

However, this exchange operator completely agrees in form with the operator (10), provided the density of the atomic core is substituted by the total density of particles. ThusFock’s method can readily be applied to the operator (10).
