Abstract

We have used the beam-foil technique to measure the decay of the 3p2P1/2,2P3/2 and 3d2D3/2,2D5/2 levels in Ar VIII and the 3s3p ‘P, 3s3d ' D, 3p1 lS, and 'D levels in Ar VII. Applying the ANDC method of analysis, accurate lifetimes for the 3p2P1/2,2P3/2 and 3s3p1P levels have been determined. The corresponding oscillator strengths are found to be in very good agreement with theoretical values. A comparison between theoretical and experimental f-values for the resonance transitions in the Na I isoelectronic sequence is also presented.
