Time-energy analysis of above-threshold ionization

Classical-quantum correspondence for above-threshold ionization.

We measure high resolution photoelectron angular distributions (PADs) for above-threshold ionization of xenon atoms in infrared laser fields. Based on the Ammosov-Delone-Krainov theory, we develop an intuitive quantum-trajectory Monte Carlo model encoded with Feynman's path-integral approach, in which the Coulomb effect on electron trajectories and interference patterns are fully considered. We...

Equal energy sharing double photo ionization of the Helium atom at 20eV and 40eV above threshold

In this article we present triple differential cross sections for equal energy sharing kinematics for double photoionization of the helium atom at 20 and 40eV above threshold in the framework of the hyperspherical partial wave theory. This supplements our earlier work [1] in which we were successful in showing fully, gauge independence of the results in our formalism. Also in this work we treat...

Equal energy sharing photo double ionization of the Helium atom at 20 and 40eV above threshold

In this article we present TDCS for equal energy sharing kinematics for double photoionization of the helium atom at 20 and 40eV above threshold in the framework of the hyperspherical partial wave theory. This supplements our earlier work [1] in which we were successful in showing fully, gauge independence of the results in our formalism. Also in this work we treat cases in which the Stokes par...

Two-source double-slit interference in angle-resolved high-energy above-threshold ionization spectra of diatoms.

When an electron from a diatomic molecule undergoes tunneling-rescattering ionization, a novel form of destructive interference can be realized that involves all four geometric orbits that are available to the electron when it is freed, because both ionization and rescattering may take place at the same or at different centers. We find experimentally and confirm theoretically that in orientatio...
