Abstract

Recent developments in bremsstrahlung from electrons colliding with atoms and nuclei at energies between 0.1 MeV and 500 MeV are reviewed. Considered are cross sections differential in the photon degrees of freedom, including coincidence geometries of photon and scattered electron. Also spin asymmetries and polarization transfer for polarized electron beams are investigated. An interpretation of the measurements in terms of the current bremsstrahlung theories is furnished.
