A SIMPLE METHOD OF TREATING INTEGRALS CONTAINING HYLLERAAS-ORE MOLECULAR FUNCTIONS

摘要

A simple method of calculation of the integrals of the Hylleraas-Ore wave function, used in the description of the four-particle system analogous to the H-2 molecule, is presented. The integrals corresponding to the kinetic energies of particles, to the Coulomb energy terms, and to the interparticle distances are given by the appropriate partial derivatives of a functional depending on the wave-function parameters.
