Model potentials for alkali metal atoms and Li-like ions

Abstract In this article we present model potential parameters for alkali metal atoms Li to Cs and the Li isoelectronic sequence. Model potentials combined with discrete variable and finite element techniques allow an accurate and quick numerical method to compute atomic data in external fields even on small computers. Results obtained for binding energies, effective principal quantum numbers, and oscillator strengths for various transitions are compared with experimental values and other theoretical computations.
