摘要：

Time-resolved laser spectroscopy was used to measure radiative lifetimes of eight excited states of neutral sulfur in a laser-produced plasma. Excitation from the atomic ground state was performed with pulsed vacuum-ultraviolet (126-140 nm) radiation generated by resonant sum-difference four-wave mixing in krypton gas. The lifetimes of the 3p(3)ns S-3 degrees (n = 5-7) and 3p(3)nd D-3 degrees (n = 4,5) states were measured and are presented together with data available from literature. Relativistic Hartree-Fock calculations of radiative lifetimes were also performed for states where experimental data were available.
