Ion Fluorescence In Cesium
Abstract
Excitation-ionization of 5p electrons in cesium by electron impact has been studied in a crossed-beam apparatus. The energy resolution of the electron beam was 0.2 eV, and the energy range was from zero to 80 eV. The vacuum ultraviolet light emitted by the excited ions was detected by a channel electron multiplier. A threshold for photon emission occurs at 17.2 eV, corresponding to the lowest ionic level excited, 5p5 6s [1 1 2], 1. The production of excited ions in cesium is partly responsible for the broad maximum that is observed in the total ionization cross section around 28 eV. © 1974.
