| Abstract: | Scattering of particles in the gravitational field of rotating black holes is considered. It is shown that scattering energy
of particles in the centre of mass system can obtain very large values not only for extremal black holes but also for nonextremal
ones. Extraction of energy after the collision is investigated. It is shown that due to the Penrose process the energy of
the particle escaping the hole at infinity can be large. Contradictions in the problem of getting high energetic particles
escaping the black hole are resolved. |
