Photo-Double Detachment of F^- and Cl^- Ions.
Abstract
We have measured absolute cross sections for the photo-double detachment of F^- and Cl^- ions. The measurements were made over the energy ranges of 20-60 eV and 18-42 eV, respectively. The experiment was performed at the Photo-Ion-Beam endstation[1] of beamline 10.0.1 at the Advanced Light Source at LBNL. The beams of halogen negative ions from an accelerator were merged co-axially with the beam of EUV photons. The measured cross sections will be compared with recent R-matrix calculations.
