Double photoionization of helium: Effect of the Coulomb repulsion on the angle-resolved cross section
Description
The effect of the Coulomb repulsion between the two ejected electrons on the angle-resolved cross section is examined; it is shown that in the general case the effective-charge approximation is not in agreement with solutions of the three-body Schroedinger equation with the appropriate asymptotic boundary conditions, and an approach is proposed in order to introduce the electron repulsion in the calculation of the sixfold differential cross section d6σ2+/d3kd3k'
