Sign of the Magnetic Moment of the Proton and of the Deuteron

Abstract

THE experiments of Stern, Estermann and Frisch, which were later corroborated by us, show that the magnetic moment of the proton is about three nuclear magnetrons. This large value indicates that the theory which accounted for the electron moment will not suffice for the proton. Further, it is well known that deflection experiments are incapable of giving an indication of the sign of the nuclear moment. In the absence of a quantitative theory, this property of the proton and of the deuteron therefore becomes a matter of assumption.
