Description
The production of high energy Eγ ∼100 MeV) gamma radiation near a black hole due to collisions of accreting protons on stable orbits is studied. The self-consistent model corresponds to spherical accretion with a low accretion rate M. The gamma radiation is due to the decay of neutral pions orbits. It is shown that mechanism may ensure a detectable gamma quantum flux from both galactic and extragalactic sources
