Polarization of Electrons by Scattering, II

Abstract

The polarization of electrons were investigated erperimentally by double scattering where the scattering angles at the polarizer and the analyzer are different. The results obtained ( -200 δ 1 δ 2 ) are 14.1±1.8, 17.0±3.0, 15.7±2.1 and 20.4±2.8 at 120 kev at angles of 105°–120°, 105°–135°, 120°, 105° and 120°–135°, and are smaller than a half of Mohr's theory. The large differences between the evidences at angles of 90°, 105°, 120° and 135°, shown in Mohr's paper, could not be obtained. The plural scattering, which is the combination of rather large angle deflections at same foil, plays an important role in this experiments, but it is difficult only by this cause to explain the discrepancy between the experiments and the theory. But the evidences by polarization increase with scattering angles, and this tendency agrees with Mohr's theory.
