Die Ortsverteilung mittelschneller Elektronen bei Mehrfachstreuung

Abstract

Several authors have investigated the angular distribution of plurally scattered electrons, but no experimental investigations in the range of plural scattering are known about the distribution of linear displacements. Therefore electrons (40 keV... 130 keV) have been shot in extended gaseous targets (He, Ne, A, Kr, Xe and O₂) of low pressure and the resultant distribution of the current density at the end of the target has been measured by means of thep−n junction of a gallium arsenide cell. The measurements in argon are compared with theoretical calculations. It is shown by some examples how to get from the measurements at the end of the target the electron distribution inside the target, too.
