Abstract: | Lifetime measurements have been carried out for some low lying (n = 2) levels in the four-electron ions Cl XIV and S XIII using the beam-foil technique. Accurate oscillator strengths for the 2 s2 1 S - 2 s 2 p 1 P o transition have been determined by the inclusion of prominent cascades in the analysis. Lifetimes of the levels of the 2 p2 3 P j multiplet have also been measured for both ions. The results are compared with theoretical predictions and earlier measurements.
