Parametrizations and Dynamical Analysis of Angle-integrated Cross Sections for Double Photoionization Including Nondipole Effects

Istomin, Andrei Y; Starace, Anthony F; Manakov, N L; Meremianin, A V; Kheifets, Anatoli; Bray, Igor


Similarly to differential cross sections for one-electron photoionization, the doubly differential cross section for double photoionization (DPI) may be conveniently described by four parameters: the singly differential (with respect to energy sharing) cross section (σ0), the dipole asymmetry parameter (β), and two nondipole asymmetry parameters (Y and δ). Here we derive two model-independent representations for these parameters for DPI from a S01 atomic bound state: (i) in terms of...[Show more]
