Particle emission rates from a black hole: Massless particles from an uncharged, nonrotating hole
Hawking has predicted that a black hole will emit particles as if it had a temperature proportional to its surface gravity. This paper combines Hawking's quantum formalism with the black-hole perturbation methods of Teukolsky and Press to calculate the emission rate for the known massless particles. Numerical results indicate that a hole of mass M very-much-greater-than 10$sup 17$ g should emit a total power output of 2 x 10$sup -4$hc$sup 6$$G$$sup -2$$M$$sup -2$, of which 81% is in neutrinos, 17% is in photons, and 2% is in gravitons. These rates plus an estimate for the emission rates of massive particles from smaller holes allow one to infer that a primordial black hole will have decayed away within the present age of the universe if and only if its initial mass was M < (5 +- 1) x 10$sup 14$ g.
