Description

The present study aims to estimate the energy and power of particles emitted by primordial black holes, which have a mass ten times smaller than the Sun.
At the first stage of the research, the maximum Lorentz factor of the electron was estimated, in particular, several mechanisms that could limit the acceleration of particles were considered, and only the mechanism that gave the lowest value was studied. It was found that such a mechanism is the particle's landing on the magnetic field line, which limits the Lorentz factor to the order of 10^5. The energy of the emitted photon was further discussed, in calculating which maximum Lorentz was used. Also, with the help of the Goldrich-Julian density, the number of particles inside of light cylinder was counted and multiplied by the radiated power of one to obtain the total radiated power. Finally, it is accepted that the energy of photons reaches 1 Tev, and electrons reaches 10^(-1) Tev, and the radiation power is 10^7 ergs⁄sec.
