The Deflection of Charged Particles in a Ferromagnetic Medium

Abstract

The deflection is recomputed which a beam of charged particles will undergo when penetrating a ferromagnetic medium whose magnetism is due to electronic spins. The extreme importance of the "interior of the electron" for the effective magnetic field b is brought out by a quantum calculation which is analogous to well-known classical considerations. Only if the interpenetration of beam particle and electron has random probability will one find b = B. Otherwisè deviations are to be expected which can be estimated in special cases. A section is added which develops the conditions under which magnetic deflection can be observed in competition with multiple scattering. Very high energy protons and deuterons offer the best possibilities (see Fig. 2).
