Photofragmentation of HCl Near the Chlorine L2,3 Threshold: New Evidence of a Strong Ultrafast Dissociation Channel
Journal of Physics B: Atomic, Molecular and Optical Physics
First page number:
We report a study using partial-ion-yield spectroscopy around the Cl 2p ionization threshold of HCl. All cation channels have been measured, while no evidence for anion production was obtained. The absence of any detectable H− can be related to the electronegativity difference between the two atoms and the observed low probability of directly creating Cl++ and Cl+++. In the photon-energy region around the Cl 2p3/2,1/2 → 6σ* excitation process, production of H+ is almost completely suppressed, which indicates a dominant ultrafast dissociation process leading to neutral H.
