Particle creation by a black hole as a consequence of quantum-field effects in flat space-time

Abstract

The application of quantum-field flat-space-time results to a black hole reveals the domain and the mechanism of particle creation. The Hawking radiation is «squeezed out» by the tail of gravitational-field potential barrier in the [1.5 Rg, ∞] region. Its black-body spectrum is due to the interaction of virtual particles with the «cavity» formed by the potential barrier. © 1985 Società Italiana di Fisica.
