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.
