The triple-differential cross section (TDCS) for the photo-double-ionization of Ne and He leading to the Ne2+(2s−22p6) and He2+(1s−2) states have been measured 20 eV above their respective thresholds in equal energy sharing conditions. The experimental results show that the Ne TDCS’s are qualitatively different from the He ones. A calculation using the convergent close coupling method with a He-like final state and different initial-state wave functions clearly shows that the observed differences can be ascribed to an initial-state effect.
