Oscillator Strengths for AI IV to Ar IX and Revised Energy Levels for Ar IX

Weighted oscillator strengths are computed for ions in the isoelectronic sequence between A1 IV and Ar IX. They were computed with a programsuite which uses the Hartree-Fock-Relativistic and Blume-Watson methods and takes into account configuration interaction. Slater parameters were optimised based on empirical data. Values of energy levels of Ar IX are revised.
