QuasiCerenkov Radiation of Relativistic Electrons in Crystals in the Presence of External Excitations

The paper is devoted to the study of the influence of crystalline lattice distortions due to external excitations (acoustic vibrations, temperature gradient, etc.) on the Quasicerenkov radiation. Equations describing Quasicerenkov radiation of charged particles in distorted crystals are derived. These equations are solved numerically. It is shown that certain types of lattice deformations may intensify the Quasicerenkov radiation by several times.
