Abstract
We have used the beam-foil technique to measure the decay of the 3p 2P1/2, 2P3/2 and 3d2D3/2, 2D5/2 levels in Ar VIII and the 3s3p 1P, 3s3d 1D, 3p2 1S, and 1D levels in Ar VII. Applying the ANDC method of analysis, accurate lifetimes for the 3p 2P1/2, 2P3/2 and 3s3p 1P 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.Keywords
