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
