Suggested Polarisation of Electrons


G. P. THOMSON1 has investigated the peculiar form of asymmetry in the scattering of electrons reported by Rupp2. According to Rupp, fast electrons when scattered first by gold through 90° and then passed through a gold foil show asymmetrical diffraction rings, while Thomson could not find any asymmetry up to the voltage of 160 k.v.
