Core-level anionic photofragmentation of OCS

Document Type



Mass spectroscopy is used to study the formation of the S-, C-, and O- anions after photoexcitation of OCS in the vicinity of the S 2p and C 1s ionization thresholds. Anions are observed both below and above these thresholds. Because anion production is known to be suppressed at core-level shape resonances, the anion measurements serve as a suggestive and complementary tool for identifying above-threshold features in OCS photoabsorption.
