Evaporation Screening, Scattering, and Quantum Tunneling Near the Horizons of Schwarzschild and Reissner-Nordstroem Black Holes

For the radial motion of massive particles with large angular momenta in Schwarzschild geometry and that of massive charged particles with largeangular momenta or energy in a particular range in Reissner-Nordstroem geometry, there exist classically forbidden regions on the outside ofthe respective event horizons which scatter certain in-falling geodesics or screen some of the black holes' evaporation by reflecting the emitted particles back into the black holes. Quantum tunneling across this forbidden regions is studied.
