The radiation reaction effects in the BMT model of spinning charge and the radiation polarization phenomenon

The effect of radiation polarization (RP) attended with the motion of spinning charge in the magnetic field could be viewed through the classical theory of selfinteraction. The quantum expression for the polarization time follows from semiclassical relation TQED ∼ ~ c/μBω c , and needs quantum explanation neither for the orbit nor for the spin motion. In our approach the polarization emerges as a result of natural selection in the ensemble of elastically scattered electrons, among which the group of particles that bear their spins in the ’right’ directions has the smaller probability of radiation.
