Photo-double ionisation of the Ne 2s studied in equal-energy-sharing condition at 20Â eV above threshold

The triple differential cross-section (TDCS) for the photo-double ionisation of Ne leading to the Ne2+(2s−22p6) has been measured 20 eV above threshold in equal-energy-sharing conditions. The results are compared with the recently introduced SC3 model, which can be used to study targets different from He since it allows an easy implementation with different initial-state wavefunctions.
