Multiconfiguration self-consistent-field calculations were performed on the following states of boron: 2s 2p, P, 2s2p, P, D, P, 2s 3s, 8, and 2p, 4S. For each state, onlyconfigurations resulting from the replacement of the valence-shell orbitals were used, and consequently only the valence-shell correlation was calculated adequately. The correlation orbital set consisted of one orbital in each of the symmetries s, p, and p (except for the 2s 3s, S state, where there were two orbitals of p symmetry). For the ground state, the value of 0.067 hartree was obtained for the valence-shell correlation energy. From the wave functions obtained, the term energies and the oscillator strengths for the allowed transitions were calculated and found to be in general agreement with the results of more elaborate calculations and experiments.

Self-consistent-field calculations have been performed by the Hartree-Fock-Roothaan method for a number of excited states of Cu and Cu + . A large number of carefully chosen and optimized Slater-type basis functions are used in order to assure a good fit to the true self-consistent-field function.
