On quantum corrections in quasiclassical theory of synchrotron radiation

A simple quasiclassical derivation of all the known quantum corrections to power of electron synchrotron radiation together with their spectral-angular distribution and polarization components is suggested. The derivation is based on the well-known properties of synchrotron radiation such as practically prompt nature of spectrum and non-inertial character of recoil effects. Matrix elements are calculated on Dirac wave functions of a free electron. Here the recoil effects are naturally separated frm radiation of proper magnetic momentum up to the second order infinitesimal by ℎ. The physical idea of quantum corrections to synchrotron radiation power becomes quite clear
