Abstract

The triple differential cross sections, TDCS, for the photodouble ionization of He, Ne, Ar and Xe leading to the He2+ (1s0 1Se), Ne2+(2s02p6 1Se), Ar2+(3s03p6 1Se)and Xe2+(5s05p6 1Se) states have been measured at about 20 eV above their respective thresholds with the two photoelectrons equally sharing the excess energy. The experimental data are analysed using a novel parametrization recently proposed. A satisfactory representation of the shape of the measured TDCS and their dependence on the increasing correlation with the principal quantum number of the ionised orbital is achieved.
