Ab initio multichannel calculation of the Bethe surface and Compton defects for molecular hydrogen
Hakon Volkmann, Alejandro Saenz
A correlated multichannel computation of the generalized oscillator-strength density for electrons scattering off randomly oriented molecular hydrogen at the internuclear separatio…

Accurate theoretical methods for photoionization of H molecules
Hakon Volkmann, Jannis Schürmann, Alejandro Saenz
Single-photon ionization cross sections of molecular hydrogen in the electric dipole limit are numerically computed by employing three independent methods. Both time-dependent and…

Potentials, exchange, and correlation in attosecond photoemission delays
Hakon Volkmann, Vinay P. Majety, Armin Scrinzi
We investigate attosecond time delays in the emission of photoelectrons using a hierarchy of models of the molecule including the strong field approximation, Coulomb-scatter…
