THE QUANTUM RADIATION FORMULAS OF A NEW RADIATION MECHANISM IN CURVEDMAGNETIC-FIELDS

A new radiation mechanism for relativistic charged particles moving in curved magnetic fields has been put forward recently by Zhang & Cheng . This radiation mechanism generalizes all the classical results of or dinary synchrotron and curvature radiation and reveals the inherent li nkage and unification between them. Since the magnitude of the pulsar magnetic field is generally similar to 10(11)-10(13) G, the quantum ef fects must be taken into account. Applying the generalized method of e quivalent photon scattering developed recently by Lieu & Axford, we pr esent the quantum-limited synchrocurvature radiation formulae in this paper, which elaborates the essence of this new radiation mechanism in a deeper sense. The formulae we present could be extensively applied to various kinds of practical curved magnetic fields, including those of pulsars.
