Comparison of the kumakhov radiation in channeling with other types of radiation

A detailed comparison is made of the Kumakhov radiation with the coherent bremsstrahlung, the transition radiation and the synchroton radiation. The coherent bremsstrahlung was shown to be suppressed under channeling conditions. It was found that the mechanism of the appearance of the Kumakhov radiation differs greatly from that for the coherent bremsstrahlung and the transition radiation. The Kumakhov radiation was shown to be more intensive than the synchrotron radiation, especially in the region of high-energy quanta.
