摘要
Two-particle collisions close to the horizon of a rotating non-extremal Kerr black hole and a Schwarzschild black hole are analyzed. For the case of multiple collisions, it is shown that high energy in the center-of-mass frame occurs due to a great relative velocity of two particles and a large Lorentz factor. We analyze the dependence of the relative velocity on the distance to the horizon and calculate the motion time from the point in the accretion disc to the point of scattering with large energy as well as the time of back motion to the Earth. It is shown that they have a reasonable order.
