Inelastic electron scattering in gases.—I

Abstract

The study of the scattering of electrons in gases has been considerably extended during the last three or four years by numerous investigators, and the results in a few cases have recently been interpreted with some success by the wave mechanics. The earlier experiments of Dymond and Watson, Harnwell, and McMillen on the angular distribution of the scattered electrons were confined to electron velocities above 50 volts and to angles of scattering smaller than 60°; the results showed only a steady decrease in the scattered intensity with increasing angle of scattering, the steepness of the curves increasing with increased electron velocity.
