  The book also describes the present measurements of the polarization parameters of the fluorescence radiation emitted by the electron-impact-excited atoms of sodium and potassium. In these investigations the target atoms are polarized, therefore, the measurements of the polarization parameters give information about the electron atom interaction in terms of the interference, direct Price: $ Get this from a library! Analysis of excitation and ionization of atoms and molecules by electron impact. [Afzal Chaudhry; H Kleinpoppen]. springer, The content of this book describes in detail the results of the present measurements of the partial and total doubly differential cross sections for the multiple-ionization of rare gas atoms by electron impact. These measurements show, beside other trends, the role of Auger transitions in the production of multiply ionized atoms in the region where the incident electron energy is.

Analysis of Excitation and Ionization of Atoms and Molecules by Electron Impact Chaudhry, Afzal Analysis of Excitation and Ionization of Atoms and Molecules by Electron Impact: Pub Date: DOI: / Electron ionization (EI), formerly known as electron impact, is an ionization method in which energetic electrons interact with gas-phase atoms or molecules to produce ions. This technique was early introduced by Dempster in [76], and is widely used for gases and volatile molecules. Optical emission is a result of electron impact excitation or dissociation, or ion impact. As an example, the SiH radical is formed by electron impact on silane, which yields an excited or superexcited silane molecule (e − + SiH 4 → SiH 4 * + e −). The excess energy in SiH 4 * is released into the fragments: SiH 4 * → SiH* + H 2 + H. The excited SiH* fragments spontaneously release their excess .   Electron impact ionization of atoms and ions is one of the most fundamental collision processes in atomic and molecular physics. Knowledge of ionization and excitation cross sections is of fundamental importance for understanding collision dynamics and electron -atom interactions, as well as in several applied fields such as radiation science, astrophysics, Auger electron spectroscopy (AES), electron energy loss spectroscopy .

Electron ionization (EI, formerly known as electron impact ionization and electron bombardment ionization) is an ionization method in which energetic electrons interact with solid or gas phase atoms or molecules to produce ions. EI was one of the first ionization techniques developed for mass spectrometry. However, this method is still a popular ionization technique.

In this article we survey some new theoretical results on (e, 2e) excitation — ionization and excitation — autoionization of ground state helium. Electron - impact ionization - excitation cross sections of helium, J. Phys. B (). Analysis of.   It is perhaps surprising that a process which was one of the first to be studied on an atomic scale, and a process which first received attention over seven decades ago, continues to be the object of diverse and intense research efforts. Such is the case with the (seemingly) conceptually simple and familiar mechanism of electron impact ionization of atoms, molecules, and ions.
