CORRELATION ENERGY OF TWO-ELECTRON SYSTEMS,
Abstract
Correlated closed-shell and open-shell functions (due to Roothaan and Weiss) are analyzed in terms of a 1/Z expansion to obtain the corresponding first order wave functions and the second order energy. The need for expanding the open-shell functions in powers of Z to the minus 1/2 power is demonstrated. The contributions to the second order energy from radial and angular correlation are estimated.
