SPECTRA OF RADIATION FOR SPINLESS AND SPIN RELATIVISTIC-PARTICLES IN STRONG MAGNETIC-FIELDS

Synchro-curvature radiation put forward by Zhang and Cheng is a new an d universal radiation mechanism, it describes in derail the radiation properties of a relativistic charged particle moving in a curved magne tic field. This new radiation generalizes ail the classical results of ordinary synchrotron and curvature radiations and reveals inherent li nkage and unification between them. Additionly, a general, simple and unitary formula is provided for discussing the radiation problem in re search of pulsars. However, the magnitude of the magnetic field of a p ulsar is so strong (10(7)-10(9)T) that the quantum effects cannot be n eglected. The GFWW method developed recently by Lieu and Axford is app lied to generalize the results of Zhang and Cheng. The quantum limited synchro-curvature radiation spectra for spinless K-G particles and sp in-1/2 Dirac particles are presented, respectively. Their radiation pr operties are also discussed.
