Title: Photoionization of the 3 s 2 3 p 4 3 P and the 3 s 2 3 p 4 1 D , 1 S states of sulfur: Experiment and theory

Journal Article · · Physical Review A - Atomic, Molecular, and Optical Physics

Photoionization of neutral atomic sulfur in the ground and metastable states was studied experimentally at a photon energy resolution of 44 meV FWHM. Relative cross section measurements were recorded by using tunable vacuum ultraviolet (VUV) radiation in the energy range 9-30 eV obtained from a laser-produced plasma and the atomic species were generated by photolysis of molecular precursors. Photoionization of this atom is characterized by multiple Rydberg series of autoionizing resonances superimposed on a direct photoionization continuum. A wealth of resonance features observed in the experimental spectra are spectroscopically assigned and their energies and quantum defects tabulated. The cross-section measurements are compared with state-of-the-art theoretical cross-section calculations obtained from the Dirac Coulomb $$R$$-matrix method. The resonances series in the spectra are identified and compared indicating similar features in both the theoretical and experimental spectra.
