Electron emission from alkali halides under soft x-ray bombardment

Abstract
An account is given of a method of measuring the yield and statistical distribution of the number of secondary electrons emitted from films of certain alkali halides under soft x-ray bombardment. The results are interpreted in terms of a theoretical model which is partly based on a Monte Carlo calculation used previously by the authors to describe the passage of low-energy electrons through thin films. Numerical values for parameters characterizing the electron-emission process are compared with results of other workers.
