Transition probabilities for the resonance transitions of Na-like ions*

Abstract

Theoretical wavelengths and transition probabilities for the 3S –3P and 3S –4P transitions of Na-like ions are presented. The theoretical data are computed from relativistic Hartree-Fock wave functions. Similar data for additional transitions between low-lying states (n = 3 and 4) of the Fe15+, Mo31+, W63+, and Au68+ ions are also reported. Relativistic effects in the oscillator strengths for the resonance transitions are qualitatively similar to those already observed in the Li sequence. Comparison with available experimental data on wavelengths for Fe15+ and Mo31+ ions shows excellent agreement (1% or better).
