ABSTRACT: The
reasons of angular photon distribution occurrence at electron-positron
annihilation are considered. It is shown that angular photon distribution is
consequence of Doppler’s effect in the reference frame of the electron and
positron mass center. In the reference frame bound with moving electron the
angular photon distribution is absent. But it is replaced by the Doppler’s
shift of photons frequencies. The received results are applied to the analysis
of a positron-emission tomograph work.
