Radiation spectrum of charged particles moving in magnetic field in a transparent medium

In this paper, we report our investigations on the spectral distribution of radiation power for the charged particles moving along an arbitrary trajectory in a transparent medium by means of Lorentz self-interaction method. Numerical calculations of the fine structure of the radiation spectrum of two electrons moving one by one in a spiral in medium were carried out in the case of relativistic transverse velocity component. We also investigated the power radiation of two electrons in a medium in terms of their placement along a spiral. From high-accuracy calculations, we obtained the spectral distribution of the synchrotron-Cherenkov radiation power of an electron moving in a spiral. The synchrotron-Cherenkov radiation is a unified process with interesting properties. (authors)
