Abstract
Recently, in the series of works a new effect of acceleration of
particles by black holes was found. Under certain conditions, the energy in
the centre of mass frame can become infinitely large. The essential
ingredient of such effect is the rotation of a black hole. In the present
Letter, we argue that the similar effect exists for a nonrotating but charged
black hole even for the simplest case of radial motion of particles in the
Reissner-Nordström background. All main features of the effect under
discussion due to rotating black holes have their counterpart for the
nonrotating charged ones.
