N2  - Electrons and positrons of energy 1 MeV were selected by a ß-ray spectrometer and scattered by a gold foil. The scattered particles were detected by a coincidence Geiger counter arrangement, using the same geometry for electrons and positrons. The results show that the ratio of the fraction of electrons scattered through an angle ? to the fraction of positrons scattered through ? varies with ?, and the magnitudes of the ratios agree with those predicted by theory. It is also inferred that there is a difference between the multiple scattering of electrons and positrons under the same scattering conditions.
