✦ Synopsis

Variational calculations were oerformed on the ground state of He and Oe. The confirmration interaction wavefunctions containing s, p_ d I&l f orbitals nre~nultiplied by the correlation factor (is+ '~~12). The best energies obtained are -2.903Gl and -59.1562 au. respectively. The s and p energy improvements combined exceed the respective anj.glar energy limits by 0.00006 au, based upon the angular energy analysis of Chandrasekhar's wavefunction by Green and coworkers.
