| 1 | The theory of bremsstrahlung from fast neutrons in electric field of atom is developed. The cross-section of process is derived. The angular and energy cross-section dependence is investigated. There are two possibilities of the photon emission: with and without neutron spin flip. Keywords: fast neutrons, bremsstrahlung | 949 | ||||
| 2 | It is considered the photon scattering by channeled positron. The process cross-section in reference frame moving with longitudinal positron velocity has been found. The angular distribution of scattered photon has been investigated. It is shown that there are three possible ways of photon scattering with positron transverse energy increasing, decreasing and without of changing positron transverse energy. Keywords: positron channeling, continuous potential, photon scattering, Compton effect | 884 | ||||
