Double photoionization .2. Analysis of experimental triple differential cross sections in helium and neon

We use the general formalism established in the companion paper I to analyse recent measurements of the triple differential cross sections for double photoionization of He and Ne, for equal energy sharing and for S-1(e) symmetry of the residual ion. A dynamical factor, which depends on the energy and on the mutual angle between the two electrons, is extracted from the experiments without relying on any dynamical approximation. This factor is expanded with respect to the one-electron angular momentum l, up to a maximum value l(max), which measures the degree of angular correlation attained by the electron pair. We discuss the physical meaning of l(max), and the dependence of the dynamical factor on the target, which is observed when comparing helium and neon results.
