THOMAS PRECESSION AND THE ELECTROMAGNETIC ANGULAR MOMENTUM RADIATION FROM THE RELATIVISTIC CHARGED PARTICLES WITH SPIN // Tomsk State Pedagogical University Bulletin. 2012. Issue 13 (128). P. 37-38

The problem of the relativistic theory of the electromagnetic orbital and spin angular momenta of the charge radiation is considered. It is obtained that the total power of the eld spin angular momentum radiation is proportional to the Thomas precession and corresponds to the force eld momentum of radiation.

ANGULAR MOMENTUM OF THE RADIATION FROM RELATIVISTIC POSITRONS AT PLANAR CHANNELING IN SI CRYSTAL // Tomsk State Pedagogical University Bulletin. 2014. Issue 12 (153). P. 9-12

The calculation of the both spin and orbital angular momenta of the radiation from 350 MeV positrons at (100) planar channeling in the ultra-thin silicon crystal is carried out by means of computer simulation. The calculations are performed as a proposal for an experimental verication at the DAFNE LINAC (INFN-LNF, Italy; energy up to 500 MeV). The possibility of the usage of the channeling radiation from relativistic positrons as the source of 4-5 MeV twisted photons is discussed.

LINEAR POLARIZATION OF RADIATION OF AN ARBITRARILY MOVING RELATIVISTIC CHARGE // Tomsk State Pedagogical University Bulletin. 2014. Issue 12 (153). P. 17-21

Exact methods of relativistic radiation theory have been used to construct indicatrixes of the angular distributions of instantaneous power radiated by an arbitrarily moving relativistic charge. It is assumed that at the moment of emission, the charge path is arbitrarily located relative to the coordinate system. The same technique has been used to study the linear polarization of radiation of an arbitrarily moving particle in the cases of curvature and fan-like radiation.
