Study of Electron-Electron Scattering

Abstract

In the course of various cloud-chamber investigations pictures of 98 electron-electron collisions were obtained, in which the primary electrons ranged in energy approximately from 0.05 to 1.7 Mev and the deflections (in the center-of-mass system) exceeded 32°. By means of a statistical test suitable for the systematic evaluation of heterogenous data, a comparison was made of our results with the theory of Møller, relativistic versions of the theories of Mott and Rutherford, and the classical non-relativistic Rutherford theory. Our data discriminate definitely only against the latter theory. When combined with 122 electron-electron collisions observed by Champion, they are consistent only with the first two theories, but are insufficient to discriminate decisively between them.
