Abstract

In this paper we present a simple method within the coupled Hartree–Fock framework to calculate the 1__s__2__s__ ^3^S state of helium and heliumlike ions. The results are in very good agreement with those obtained by the use of multiterm correlated wave functions. Some interesting observations associated with the wave function are presented.

## Abstract A simple self consistent variation perturbation method in the coupled Hartree–Fock scheme has been proposed to calculate 1__s__2__s__ ^1^__S__ state of the He atom. The present paper deals with an 1__s__2__s__ ^1^__S__ wave function in which all the relevant orthogonality conditions are
