Principles and procedures for determining absolute differential electron-molecule (atom) scattering cross sections
TLDR
In this article, the absolute elastic and inelastic differential cross sections (DCS) for electron impact on molecular (atomic) species are described and illustrated by examples, and a method of determining absolute differential electron-molecule scattering cross sections is generally applicable and provides reliable results.Abstract:
Procedures and calibration techniques for measuring the absolute elastic and inelastic differential cross sections (DCS) for electron impact on molecular (atomic) species are described and illustrated by examples. The elastic DCS for the molecule under study is first determined by calibration against helium using the relative flow technique. The second step involves the production of energy-loss spectra for the instrument response function, the unfolding of overlapping inelastic structures and the normalization of inelastic intensities to the elastic cross sections. It is concluded that this method of determining absolute differential electron-molecule (atom) scattering cross sections is generally applicable and provides reliable results.read more

The Threshold Law for Single Ionization of Atoms or Ions by Electrons
TL;DR: In this paper, the dependence of the yield on the energy just above a threshold is derived and the derivation is not rigorous because it circumvents some of the difficulties of the three-body problem by applying ergodicity, albeit in a weakened form.

TL;DR: In this paper, the Schrodinger equation for two electrons in a Coulomb field is studied in the critical region where both electrons have near-zero kinetic energies, and the main feature of this problem is that the mutual screening between the two electrons determines and is determined by the partition of the available energy between them.
