A multicoincidence electron-electron spectrometer has been modified by including two ion detectors in order to enable both photoelectron-Auger electron and photoelectron (or Auger electron)-ion coincidence measurements as a substantial step towards a complete experiment. Results of the first use of this set-up to study the photoelectron-Auger electron angular correlations and photoelectron angular distributions of "fixed-in-space" molecules in the case of the C 1s ionization of the CO molecule are presented and compared with theoretical calculations in the Hartree-Fock approximation based on the two-step model.

Abstract
A multicoincidence electron-electron spectrometer has been modified by including two ion detectors in order to enable both photoelectron-Auger electron and photoelectron (or Auger electron)-ion coincidence measurements as a substantial step towards a complete experiment. Results of the first use of this set-up to study the photoelectron-Auger electron angular correlations and photoelectron angular distributions of "fixed-in-space" molecules in the case of the C 1s ionization of the CO molecule are presented and compared with theoretical calculations in the Hartree-Fock approximation based on the two-step model.File in questo prodotto:
