Electron angular distributions in the two–photon ionization of hydrogen–like ions: relativistic description‡
The angular distribution of the emitted electrons, following the two– photon ionization of the hydrogen–like ions, is studied within the framework of second order perturbation theory and the Dirac equation. Using a density matrix approach, we have investigated the effects which arise from the polarization of the incoming light as well as from the higher multipoles in the expansion of the electr...
متن کاملSubcycle control of electron-electron correlation in double ionization.
Double ionization of neon with orthogonally polarized two-color (OTC) laser fields is investigated using coincidence momentum imaging. We show that the two-electron emission dynamics in nonsequential double ionization can be controlled by tuning the subcycle shape of the electric field of the OTC pulses. We demonstrate experimentally switching from correlated to anticorrelated two-electron emis...
متن کاملProbing electron correlation via attosecond xuv pulses in the two-photon double ionization of helium.
Recent experimental developments of high-intensity, short-pulse extreme ultraviolet light sources are enhancing our ability to study electron-electron correlations. We perform time-dependent calculations to investigate the so-called "sequential" regime (variant Planck's over 2piomega > 54.4 eV) in the two-photon double ionization of helium. We show that attosecond pulses allow us not only to pr...
متن کاملFirst observation of two-electron one-photon transitions in single-photon K-shell double ionization.
Experimental evidence for the correlated two-electron one-photon transitions (1s(-2)→2s(-1)2p(-1)) following single-photon K-shell double ionization is reported. The double K-shell vacancy states in solid Mg, Al, and Si were produced by means of monochromatized synchrotron radiation, and the two-electron one-photon radiative transitions were observed by using a wavelength dispersive spectromete...
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...
