Analytic Hartree-Fock wave functions for the 3p-shell atoms

Hartree-Fock wave functions have been obtained for the 3p-row atoms, i.e., for neutral Al, Si, P, S, Cl, and Ar, and for Cl-. Solutions were determined in analytic form using a version of Nesbet's symmetry and equivalence restrictions to simplify the calculations for atoms with both closed and unclosed shells of the same l value. These restrictions, the reason for their use, and their relation to other open-shell methods are discussed and the calculated one-electron wave functions and their eigenvalues are presented.
