The matrix elements for two-photon transitions involve a sum over intermediate states. It is well known that where the initial and/or final states have permanent electric moments these appear in the sum, and contribute to the transition rate. For irradiation with different frequencies, the behaviour

Relative contributions of parametric X-rays and diffracted bremsstrahlung to the emission from relativistic electrons penetrating a crystal under Bragg scattering condition is studied theoretically. It is shown that the diffracted bremsstrahlung contribution may be essential under special conditions
