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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
