Photoionization of xenon below the atomic ionization potential

Improved Upper Bounds for the Atomic Ionization Potential

Two sets of rigorous upper bounds on the atomic ionization potential are derived from some known inequalities of the classical analysis. The first set of bounds are expressed in terms of radial expectation values of the electron density; they improve previously found bounds of the same kind and converge to the exact ionization potential. The other bounds depend on various atomic density functio...

Trends in the theory of atomic photoionization.

For VUV photon energies, detailed theoretical understanding of the photoionization process has been achieved for the case of a single electron ionized from one of the outer subshells of a closed-shell atom. This understanding is based qualitatively upon a few properties of realistic atomic central potentials and quantitatively upon a few distinct types of electronic interactions known generical...

Photoionization and electron-impact ionization of Xe3+

Where does atomic photoionization begin?

We perform a time-delay analysis of of strong field ionization of atomic hydrogen in the tunnelling regime. We obtain the values of the time delay from the quantum-mechanical calculation involving solution of the time-dependent Schrödinger equation, and use these values as parameters defining corresponding classical trajectories. We demonstrate that almost all the classical trajectories, define...
