Hawking radiation of charged particles via tunneling from the Reissner-Nordstrom black hole

Hawking radiation is viewed as a tunneling process. In this way the emission rate at which charged massive particles tunnel across the event horizon of the Reissner-Nordstrom black hole is calculated. The emission spectrum deviates from the pure thermal spectrum, but it is consistent with an underlying unitary theory and takes the same functional form as that of uncharged massless particles.
