Spin light identification in the presence of power synchrotron radiation

The relativistic radiation theory of the intrinsic magnetic moment of an electron (which is known as spin light) from the point of view of the correspondence principle of classical, semi-classical and quantum theory of radiation is discussed. It is shown that after separation of terms unbound with a spin in the power of the total radiation of electrons (with the example of the synchrotron radiation of an electron) the correspondence principle holds accurate within a second approximation by Plank's constant. The formulas for the angular distribution, linear polarization and spectral structure of radiation obtainable here with an allowance for spin can find application for non-trivial problems of experimental identification of spin light.
