QUANTUM-LIMITED SYNCHROTRON-RADIATION IN INHOMOGENEOUS MAGNETIC-FIELDS

A generalized method of equivalent photon scattering suitable for the problem of emission from a continuously accelerated charge was success fully applied to demonstrate that synchrotron radiation is fundamental ly an inverse-Compton effect. Here we present an improved derivation o f the classical emissivity and explain in more detail some of the impo rtant steps in the quantum derivation. Moreover, we extend this method to derive the emissivity of a charge in arbitrary relativistic motion , including quantum recoil corrections.
