is shown. by comparison with experiment, that the use of explicit angular momentum coupling in Hartree-Fock solutions for rare-earth ions can lead to inaccurate 4f radial wave-functions beCaUSe of the neglect of intershell correlation effects.

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.
