Abstract
We report mean-life results for 16 terms in S III–S VI, obtained from vacuum ultraviolet transitions in sulfur excited by beam–foil interaction. Ten of the mean lives have been measured for the first time. Many of the mean lives reported here are in the neighborhood of 0.1 ns, beyond the time resolution capability of a previous experiment, as indicated by comparison of results for five of the remaining six terms. For those transitions that are unbranched. we have computed the absorption oscillator strength and we discuss the values in the context of isoelectronic-sequence trends. In an appendix, we discuss the determination of short mean lives and describe the apparatus we have developed to measure them, and its limitations.
