Abstract
IN the November 1925 issue of the Physical Review, Langmuir published an investigation under the above title. From the collector characteristics of a mercury vapour discharge with a hot cathode, it was concluded that, in the tube, electrons must have been present with abnormally high velocities. Langmuir expressly mentions that with these discharges no oscillations could be found. In several experiments which were made by me in consequence of this publication, oscillations could in fact be detected. In accordance with my results, summarised below, it does not seem impossible that the observed “scattering of primary electrons” is always accompanied and caused by these oscillations.
