Determination of radiative lifetimes of neutral sulphur by time-resolved three-photon VUV laser spectroscopy
(1998) In European Physical Journal D. Atomic, Molecular, Optical and Plasma Physics 2(1). p.11-14- Abstract
- Radiative lifetimes of the highly exited states 3p(3)8s S-3(1)0 and 3p(3)6d D-3(1,2,3)0 of neutral sulphur have been measured using time-resolved laser-induced fluorescence. The sulphur atoms were generated in a laser-produced plasma. The investigated states were populated through a two-step process involving a two-photon excitation to the lowest excited tripler state of even parity 3p(4) P-3(0,1,2), followed by a one-photon excitation to the investigated state. We obtained tau(8s(3)S(1)(0)) = 40 +/- 5 ns and tau(6d(3)D(1,2,3)(0)) = 75 +/- 7 ns. These values are much longer than theoretically predicted ones and much shorter than those indirectely inferred from astronomical data.
