Abstract:

Adopting Parikh’s mode of quantum radiation as tunneling, the tunneling radiation characteristics of NUT- Kerr- Newman black hole is studyed. When energy conservation and angular momentum conservation are taken into account, the real spectrum of stationary NUT- Kerr- Newman black hole is not precisely thermal at all and the tunneling rate of the particle on the event horizon relates to the change of Bekenstein- Hawking entropy, which is consistent with underlying unitary quantum theory.

Key words: NUT- Kerr- Newman black hole, Energy conservation, Angular momentum conservation, Bekenstein-Hawking entropy, Tunneling rate
