Direct two-photon double ionization of helium
The role of electron correlation, i.e. the electron-electron repulsion, in non-sequential two-photon double ionization of helium has been widely debated in literature, and the issue is not yet fully resolved. We present total cross sections for this process obtained within a one dimensional model of the helium atom. In our calculations the cross sections are obtained in two ways. Firstly, the t...
متن کاملPolarization control of direct (non-sequential) two-photon double ionization of He
An ab initio parametrization of the doubly-differential cross section (DDCS) for twophoton double ionization (TPDI) from an s2 subshell of an atom in a S0-state is presented. Analysis of the elliptic dichroism (ED) effect in the DDCS for TPDI of He and its comparison with the same effect in the concurrent process of sequential double ionization shows their qualitative and quantitative differenc...
متن کاملAngular anisotropy parameters for sequential two-photon double ionization of helium
We evaluate photoelectron angular anisotropy parameters for the process of sequential two-photon double electron ionization of helium within the lowest-order time-independent perturbation theory. Our results indicate that for photoelectron energies outside the interval Eslow,Efast , where Eslow= −VHe+ and Efast= −VHe, there is a considerable deviation from the dipole angular distribution, thus ...
متن کاملPhotoelectron angular correlation pattern in sequential two-photon double ionization of neon
We apply an angular momentum coupling formalism to describe the angular correlation pattern in sequential two-photon double ionization of neon. Comparison with previous work [Fritzsche et al. J. Phys. B 41, 165601 (2008)] reveals some important differences which are discussed in terms of various ionization mechanisms and their theoretical implementations in two alternative approaches PACS numbe...
متن کاملTwo-photon double ionization of He and H−
Two-photon absorption processes resulting in two-electron ionization of He and H− are calculated using a time-dependent close-coupling expansion on a two-dimensional radial lattice. The ground state atom or ion is subjected to a 10-cycle pulse of linearly polarized light with peak intensities ranging from 1013 to 1016 W cm−2. Probabilities are calculated for onephoton single ionization, two-pho...
