Photodouble ionization studies of the Ne(2s2) state under unequal energy sharing conditions
The triple differential cross section (TDCS) of the He2+(1s-2) and Ne2+(2s-2) states has been studied under unequal energy sharing conditions and perpendicular geometry, for a ratio of about 3 between the energies of the two ejected electrons. The dynamical quantities which govern the photodouble io...

Zusammenfassung: | The triple differential cross section (TDCS) of the He2+(1s-2) and Ne2+(2s-2) states has been studied under unequal energy sharing conditions and perpendicular geometry, for a ratio of about 3 between the energies of the two ejected electrons. The dynamical quantities which govern the photodouble ionization (PDI) process, i.e. the squared moduli of the gerade and ungerade complex amplitudes and the cosine of their relative phase, have been extracted from the experimental data. The results from the two targets have been compared between themselves as well as with the theoretical predictions of the SC3 and convergent close coupling (CCC) calculations. This work represents a joint experimental and theoretical approach to the investigation of PDI of atomic systems with more than two electrons. |
