Vibrational Excitation of Molecules By Slow Electrons

  • Chapter
Electron-Molecule Collisions

Part of the book series: Physics of Atoms and Molecules ((PAMO))

Abstract

This chapter deals with the excitation of vibration in a molecule by the impact of an electron with an energy of a few electron volts, rarely as high as 30 eV. The field has been reviewed so many times in the last 10 years(1-11) that another paper-by-paper review hardly seems appropriate. What does seem appropriate is an elementary exposition of the physical concepts, particularly resonances and virtual states, which lie behind much of the discussion. These concepts are understood very well by the very few people who actually use them in calculations, but unfortunately different people speak and write about them in ways which at first sight seem to be describing different physical objects. Lengthy discussion usually leads to the conclusion that everyone is talking about the same physics, but it is at present difficult for the newcomer to the field to see this because there is a lack of elementary introductions. This chapter, then, is an attempt at such an elementary introduction. The reader who wants to know more about current theoretical developments will find it helpful to go to the published reviews, starting with the most recent, by Lane(1) and Burke.(2) The reader who wants to know how the experiments are done will find a good starting point in the papers(11) on the state of the experimental art at the first and second Schulz Symposia, by Linder (in 1977) and Read (in 1979).
