Type-B (axial) coherent bremsstrahlung spectra have been obtained with an energy resolution of 42 eV. These show a type of fine structure, due to the contributions of Umklapp events from different reciprocal-lattice vectors in the same reciprocal-lattice plane normal to the beam, not passing through the origin. A plane-wave theory fits the data well if atomic scattering factors for isolated atoms are used. The observation of crystal bonding (solid-state relaxation) effects on the coherent-bremsstrahlung intensities requires a more sophisticated theory for the treatment of the continuous background. Bloch-wave broadening effects are not seen at this resolution.
