On the grounding of spin effects in theory of synchrotron radiation

Abstract

The problem of the uniqueness in the introduction of spin operators in the synchrotron radiation (SR) theory is discussed. For this purpose we give the invariant spin projections on the basis of the spin projections in the rest frame. The spin equations are used to construct the integrals of motion in the presence of the external electromagnetic field.PACS 03.65.Sq -Semiclassical theories and applications.
