Inner bremsstrahlung processes. II

The paper starts the study of magnetic inner bremsstrahlung by considering the overall constraints imposed by energy and momentum conservation as well as the restrictions implied by the explicit and 'accidental' symmetries associated with the unbounded uniform field. The role of hyperdegeneracy and quantum effects is discussed. Magnetic pair procuction by virtual photons is then considered. Finally, the three variations of ordinary magnetic bremsstrahlung: (i) Cerenkov-magnetobremsstrahlung; (ii) quantum fluctuations; and (iii) pair production and rho0 production, are considered.
