Oscillator strength measurements of the resonance transitions in sodium- and magnesium-like argon

Summary, in English

We have used the beam-foil technique to measure the decay of the 3p²P_1/2,²P_3/2 and 3d²D_3/2,²D_5/2 levels in Ar VIII and the 3s3p ‘P, 3s3d ' D, 3p^{1 l}S, and 'D levels in Ar VII. Applying the ANDC method of analysis, accurate lifetimes for the 3p²P_1/2,²P_3/2 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.
