Intrinsic Moments of Elementary Particles
Abstract
A system described by a firstorder linear field equation, with matrix coefficients satisfying the general commutation rules of degree n derived by Bhabha, is assumed to interact with an external electromagnetic field. By manipulation of permutations of the operators involved, a systematic procedure is developed for extracting the intrinsic moments of a system of arbitrary n; such moments are found to exist up to and including 2^{n1}pole order. The (covariant) interactions are simplified by considering the system in one of its rest states. An explicit formula for the magnetic dipole moment is derived and compared with the result obtained for a special case by HarishChandra.
