(e,2e) spectroscopy
TL;DR: In this article, the conditions necessary to extract momentum-density information from the ionization experiments are examined and related to general theories of electron scattering, and different experimental arrangements are reviewed and momentum density results from selected examples are discussed.
Journal ArticleDOI
Electron momentum spectroscopy of atoms, molecules, and thin films
TL;DR: 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 presented in this paper.

A D Smith,Michael A. Coplan,Dennis J. Chornay,John H. Moore,John A. Tossell,J Mrozek,Vedene H. Smith,N. S. Chant +7 more
TL;DR: In this paper, the effect of distortions on the (e, 2e) spectroscopy of helium is examined, and it is found that distortions contribute significantly to the cross section for transitions to both the n=1 ground state and n=2 first excited states of He+ at incident energies as high as 1200 eV.

Multichannel (e,2e) apparatus.
TL;DR: An apparatus for the coincident observation of both outgoing electrons in an electron impact ionization, or (e,2e), experiment, which employs ten detectors arranged such that every pair corresponds to a different set of momenta for the outgoing electrons intercepted by that pair.
