## 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
## 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 o
