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

TL;DR: Differential and integral cross sections for electron-impact excitation of the dipole-allowed electronic states of molecular hydrogen have been measured in this article, where the cross sections were determined by analysis of normalized energy-loss spectra obtained using a crossed-beam apparatus at the electron impact energies of 40, 100, and 200 eV.

Experimental differential cross sections for the electron impact excitation of the a 1Deltag, b 1Sigmag+, and the 6 eV states of O2
TL;DR: In this paper, absolute differential cross sections for the excitation of the 1Deltag and b 1Sigmag+ states in O2 were measured at 90 degrees, and in some cases at 30 degrees as a function of electron energy from threshold up to about 18 eV and, at 4.5 and 7.5 eV, as the scattering angle from 10 degrees to 135 degrees.

Absolute elastic electron scattering from benzene
Robert J Gulley,Stephen Buckman +1 more
TL;DR: In this paper, the angular distribution of elastic electron scattering from benzene (C6H6) was investigated for incident electron energies of 8.5 and 20 eV, and the angular distributions were discussed in terms of known negative ion resonance features and a favourable comparison was made with a recent model potential calculation.

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.

Two electrons in a coulomb potential. double-continuum wave functions and threshold law for electron--atom ionization.
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.
