Abstract

The lifetime of the 3s3p1P term in Mg-like S V has been determined by beam-foil spectroscopy in combination with detailed analyses of cascading processes by means of the ANDC technique. One of the most important cascade transitions was found to be seriously blended by a strong S VII transition. An earlier proposed method for appling the ANDC formalism to correct for blending has been tested for the first time and found to work very well. The resulting 3s3p1P lifetime of 0.19 ± 0.01 ns, corresponding to an absorption oscillator strength of 1.46 ± 0.08, is in good agreement with recent theoretical values. Some previously noted discrepancies between beam-foil measurements and theoretical calculations for Mg-like ions... (More)

An earlier proposed method for appling the ANDC formalism to correct for blending has been tested for the first time and found to work very well. The resulting 3s3p1P lifetime of 0.19 ± 0.01 ns, corresponding to an absorption oscillator strength of 1.46 ± 0.08, is in good agreement with recent theoretical values. Some previously noted discrepancies between beam-foil measurements and theoretical calculations for Mg-like ions can now be explained as being due to insufficient cascade corrections in previous experimental work.
