Coherence and magnetic-bremsstrahlung effects in radiation by relatlvistic particles moving in a crystal near a crystallographic axis
Shul'ga N. F.
It is predicted that the intensity of radiation from relativistic particles moving in a crystal at energies exceeding the barrier energy (superbarrier particles) will be much higher than that from particles moving in an amorphous medium. A number of results obtained in experiments on radiation by channeled particles are explained. New experiments are proposed to detect the predicted effect.
