- 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.

- Experimental lifetimes of several levels in the 2p5 3p and 3d configurations in Ne-like sulphur, S VII, and argon, Ar IX, have been determined by the beam-foil technique. The ANDC method for cascade correction has been applied in the analyses of the 3p decay curves. The results are generally in good agreement with recent theoretical values except for the 3p 3D levels for which significant deviations are observed. Similar discrepancies have also been observed in the isoelectronic Cl VIII system.
