Resonance-Enhanced Multiphoton-Ionization Photoelectron-Spectroscopy of Even-Parity Autoionizing Rydberg States of Atomic Sulfur
Several previously unobserved Rydberg states of the sulphur atom above the lowest ionization threshold are identified and assigned using (2 + 1) resonance-enhanced multiphoton-ionization photoelectron spectroscopy. All states were accessed by two-photon transitions from either the P-3 ground or the D-1 excited state, prepared by in situ photodissociation of H2S. The observed states derive from the (D-2(0))5p and (P-2(0))4y configurations. For the (D-2(0))5p F-3 and (P-2(0))4p D-3 triplets, extensive photoelectron spectroscopic studies enable a detailed comparison of the autoionization and photoionization rates of these states.
