Interactions ofμ-Mesons

Abstract

The energy spectrum of electrons knocked on by $\mu$-mesons has been measured over a wide range of energies. It is found that the theoretical cross section as derived by Bhabha fits the data for knock-on energies of a few Mev up to energies of the order of a Bev. From these data it is concluded that any particle structure that might exist does not appreciably affect collisions with impact parameters of 6×${10}^{-13\mathrm{}}$ cm or more.
