Abstract: We give new estimates for the possibility that a resonance appears in the center-of-mass system when particles collide in the ergospheres of rotating black holes—active galactic nuclei. We investigate a new effect: an increase in the center-of-mass energy depending on the particle angular momentum, which can occur at any point of the ergosphere.

Keywords: black hole, Kerr metric, particle collision, geodesic.
