Probing angular correlations in sequential double ionization.

چکیده
We study electron correlation in sequential double ionization of noble gas atoms and HCl in intense, femtosecond laser pulses. We measure the photoelectron angular distributions of Ne+ relative to the first electron in a pump-probe experiment with 8 fs, 800 nm, circularly polarized laser pulses at a peak intensity of a few 10(15) W/cm2. Using a linear-linear pump-probe setup, we further study He, Ar, and HCl. We find a clear angular correlation between the two ionization steps in the sequential double ionization intensity regime.

Probing 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 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 کاملCriterion for Distinguishing Sequential from Nonsequential Contributions to the Double Ionization of Helium in Ultrashort Extreme-Ultraviolet Pulses.
We quantify sequential and nonsequential contributions in two-photon double ionization of helium atoms by intense ultrashort extreme-ultraviolet pulses with central photon energies ℏω_{ctr} near the sequential double-ionization threshold. If the spectrum of such pulses overlaps both the sequential (ℏω>54.4 eV) and nonsequential (ℏω<54.4 eV) double-ionization regimes, the sequential and nonseque...
متن کاملProbing orbital symmetries and ionization dynamics of simple molecules with femtosecond laser pulses
It is shown that by measuring the angular distributions of fragmented ions of simple molecules by sub-10 fs laser pulses at intensities in the non-sequential double ionization regime the electron density of the highest occupied molecular orbital can be probed directly. It is also shown that using a single laser pulse, from the kinetic energy release of the fragmented ions following the double i...
