Atomic Densities, Polarizabilities, and Natural Orbitals Derived from Generalized Sturmian Calculations

Research output: Contribution to journalJournal articleResearchpeer-review

The generalized Sturmian method for atomic and
molecular electronic structure calculations is a direct configuration
interaction method in which the configurations are chosen to be
isoenergetic solutions of an approximate N-electron Schrödinger
equation with a weighted potential, $\beta_\nu V_0$. The weighting
factors $\beta_\nu$ are especially chosen so that all the
configurations in the basis set correspond to the same energy
regardless of their quantum numbers. In this paper, the generalized
Sturmian method is used to calculate excited states, densities,
polarizabilities, and natural orbitals of few-electron atoms and ions.
