Analytical Self-Consistent Field Functions for Positive Ions. I. Isoelectronic Series with 2 to 10 Electrons

Abstract

Analytical self‐consistent field (SCF) functions for the neutral atoms and positive ions isoelectronic series of 2 to 10 electrons up to Z=36 are presented. These computations deal with the lowest electronic configuration ground states and excited states. The basis set of Slater‐type orbitals (STO) is fully optimized with respect to the orbital exponent, and considerable effort was given to obtain a short expansion. A maximum of nine STO's were considered sufficient for the largest expansion. The total energies of each isoelectronic series are collected in simple series expansions in power of Z. For the 444 computed SCF functions here reported, only the most important features are discussed.
