A comparison is presented for the ground state of the helium atom of high order Rayleigh-Schri)dinger perturbation theories based upon a hydrogenic. a screened hydrogenic, a Hartree and a modified Hartree local zero-order hamiltonian. The hydrogenic zero-order schemes are superior tc the Hartree zer
## 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
