An experiment was carried out to find out the palarization of electrons by double scattering. The scatterers used were gold foils of 5×10^<-5> mm thick and the energy of electrons ranged from 45 to 92 kev. The scattering angle at the first foil was taken as 90 degrees and that at the second foil 78 degrees. Polarization effect, as predicted by Mott, has been found, though its magnitude was somewhat smaller than that given by the theory. The values of 200δ obtained was 3.6±1.0, 4.0±0.9, 6.8±0.7, 9.0±0.6, and 9.1±1.0 for the electrons of energy 45, 60, 70, 90, and 92 kev, respectively.
