We have carried out calculations of the triple-differential cross section for one-photon double
ionization of molecular hydrogen for a central photon energy of 75 eV, using a fully ab initio …

Our previously developed finite-element discrete-variable representation in prolate
spheroidal coordinates is extended to two-electron systems with a study of double ionization …

For the ionization of diatomic molecules the conditions and mechanisms giving rise to large
positive and negative time delays of the ejected electrons are studied. It is shown that for H 2 …

The calculation of triple-differential cross sections for the electron-impact ionization of 10 a′
and 2 a′′ orbitals of the formic acid (HCOOH) molecule has been carried out by the …

We apply the concept of photoemission time delay to the process of single-photon one-
electron ionization of the H 2 molecule. We demonstrate that, by resolving the photoelectron …

A multicenter distorted-wave method is used to study the electron impact single ionization
from the outer (1 t 2) and inner (2 a 1) valence orbitals of a CH 4 molecule. The triple …

A combined basis of analytic Gaussian functions and grid-based finite element-discrete
variable representation spherical harmonic expansion is specialized for the description of …

Abstract The (e, 3–1e) four-fold differential cross sections (4DCS) are measured for the
double ionization of helium in coplanar asymmetric geometry for a wide range of ejected …

The present work deals with photoionization in the realm of the absorption of one single
photon. The formal treatment of one-photon ionization usually employs a semi-classical …

We report on kinematically complete measurements and ab initio nonperturbative
calculations of double ionization of He and H 2 by a single 800 eV circularly polarized …
