Several experimental groups have recently obtained the so-called vortex electrons (electrons with orbital angular momentum (OAM) of ℓ ≤ 100ħ) with energies of ∼ 300 keV. The angular momentum of such electrons becomes proportional to the OAM value, which leads to the corresponding increase in the electron magnetic moment. In this work, we investigate the transition radiation from the “charge + magnetic moment” system by means of the classical electrodynamics theory. The circular polarization of optical transition radiation reaches its maximum level to ∼ 70%, which allows using this effect for the independent measurement of the electron orbital momentum value.
