Most of our knowledge of the electronic structure of atoms and molecules is derived from
excitation energies and transition probabilities. These observable quantities are related to …

The latest, most important developments in (e, 2e) studies are reviewed from an
experimental point of view. These include ionization processes near threshold, the …

Photoelectron (PE) spectroscopy has long since been a versatile tool to investigate the
electronic structure of atoms, molecules, solids, and surfaces.'-'More recently the classic …

The experimental and theoretical situations for direct single ionization by electron impact are
reviewed with special emphasis on triple differential cross sections for impact energies …

A review of the theory of electron momentum spectroscopy (EMS) based on the single
(multiple) electron impact ionization of a quantum target (atom, molecule, thin film) is …

High-accuracy absolute triple differential cross sections for ionisation of molecular hydrogen
by approximately 4 keV electron impact have been measured in a coplanar asymmetric …

Abstract The (e, 2e) cross section for electron impact ionization of the hydrogen molecule
has been measured with a precision of a few percent at 400 eV incident energy. The …

The triple differential cross section (3DCS) for the (e, 2 e) ionization of diatomic hydrogen is
determined using the first-order transition matrix element of the Born series. A two-effective …

The double processes of He in electron-impact ionization, single ionization with
simultaneous excitation and double ionization, have been studied at large momentum …

Abstract The absolute (e, 2 e) triply differential cross sections measured in coplanar
nonsymmetric conditions are reported for the intermediate 2 p orbital of Ar, at an incident …
