Popis:	The production of narrow beams of high-energy gamma quanta in the process of resonant spontaneous bremsstrahlung radiation of ultrarelativistic electrons on nuclei in strong electromagnetic fields is predicted. This effect is realized under special experimental conditions for the frequencies and intensities of the laser installation. Resonant differential cross sections with simultaneous registration of the outgoing angle and the energy of the spontaneous gamma quantum, as well as a small number of absorbed photons of the wave, can exceed the corresponding differential cross section without an external field by 18–19 orders of magnitude. The obtained results can be used to obtain narrow beams of high-energy gamma quanta, as well as to explain high-energy gamma quanta near pulsars and magnetars.
