Variational calculations were oerformed on the ground state of He and Oe. The confirmration interaction wavefunctions containing s, p\_ d I&l f orbitals nre~nultiplied by the correlation factor (is+ '~~12). The best energies obtained are -2.903Gl and -59.1562 au. respectively. The s and p energy imp
## Abstract The difference in the electron correlation between H^‐^ and other two‐electron atoms is clarified by the introduction of the __r__~12~ term in the wave function. By using the expansion of __r__~12~, a certain modification of the usual electron correlation factor 1 + __Cr__~12~ is introd
Two points about correlation potentials have been dealt with in this article. The first one is related to the shape of some of the most representative correlation potentials applied to the ground state of the He atom. It is shown here that both LDA and two-body density correlation potentials compare
