Atomic and Molecular Calculations with the Pseudopotential Method. VII One-Valence-Electron Photoionization Cross Sections

The pseudopotential method is applied to evaluate $p$ continuum wavefunctions for a number of atomic one‐valence‐electron systems. Combining the continuum $p$ results with the ${\mathrm{ns}}^{2}S$ ground states previously calculated, the photoionization cross sections for the $\mathrm{ns–\epsilon p}$ transitions of each system are evaluated. The following atoms and ions are investigated with the indicated continuum energy range above the ionization threshold: Li, Be⁺, B²⁺, C³⁺, Na, Mg⁺, Al²⁺, and Si³⁺ from 0–2.0 Ry; K, Ca⁺, and Rb from 0–0.6 Ry; and Cu, Zn⁺, and Ag from 0–0.8 Ry. Comparison is made to other calculated values with good agreement and to the observed values of Li, Na, K, and Rb with reasonable agreement.
