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
The Hartree-Fork limit for the ground state of the He atom is rediscussed on the basis of the generator-coordinate Hartree-Fock method and the Laplace transform. A numerical solution is implemented which leads to a value of 73 x 1O-'2 hartree below the commonly accepted limit.
