THE INFLUENCE OF THE ANOMALOUS MAGNETIC MOMENT ON THE SPIN KINEMATICS OF ELECTRONS IN A UNIFORM MAGNETIC FIELD
The influence of a uniform magnetic field on thc spin orientation of electrons, or other spin 1/2 particles, in a beam is computed by assuming that the Dirac--Pauli equation correctly represents the electrons having anomalous magnetic moment. It is shown that, when the fieid is orthogonal to the electron beam, the anomalous magnetic moment causes the spin to turn about the field direction faster than in the normal condition. This effect depends on the energy of the electrons and becomes particularly large for energies which are high compared with the rest mass: for about 250 Mev energies a half circle path in the field would suffice to convert the longitudinal polarization state of the beam into the transverse one. The calculations are performed by making use of the exact solution of the Dirac-Pauli equation. (auth)
