摘要：

We describe the three-body final state resulting from the photo-double-ionization (PDI) of two-electron ionic atoms by a modified C3 wave, denoted SC3. This continuum wave function accounts for the nuclear dynamical screening in the inter-electronic motion. We analyze the scaling properties of the triply differential cross-sections (TDCS). For an easier comparison with possible experimental results we analyze the correlation factor in the Gaussian parametrization of the TDCS, for different nuclear charges. We determine the dependence of the half width at half maximum of the Gaussian with the nuclear charge and discuss possible physical mechanisms.
