Two-photon double ionization of helium in the region of photon energies 42-50 eV
I. A. Ivanov, A. S. Kheifets
We report the total integrated cross-section (TICS) of two-photon double ionization of helium in the photon energy range from 42 to 50 eV. Our computational procedure relies on a n…

Different escape modes in two-photon double ionization of helium
A. S. Kheifets, I. A. Ivanov, Igor Bray
The quadrupole channel of two-photon double ionization of He exhibits two distinctly different modes of correlated motion of the photoelectron pair. The mode associated with the ce…

Convergent close-coupling calculations of two-photon double ionization of helium
A. S. Kheifets, I. A. Ivanov
We apply the convergent close-coupling (CCC) formalism to the problem of two-photon double ionization of helium. The electron-photon interaction is treated perturbatively whereas t…
