Radiation Bursts from Particles in the Field of Compact, Impenetrable,   Astrophysical Objects
  The radiation emitted by charged, scalar particles in a Schwarzschild field with maximal acceleration corrections is calculated classically and in the tree approximation of quantum field theory. In both instances the particles emit radiation that has characteristics similar to those of gamma-ray bursters.
