Absolute Cross Sections for the Elementary Process of Bremsstrahlung ProductionBremsstrahlnng cross sections differential in electron angle, photon angle and energy have been determined for silver. The energy of the incident electrons was 180 keV, this of the scattered electrons 100 keV. Within the experimental errors we found agreement with the results of the calculations of Elwert and Haug.

Coincidence measurements of the absolute cross section for the production of bremsstrahlung by electrons in the field of gold atoms are reported. The incident electron energy T o was 300keV. Measurements were made for four different combinations of electron scattering angle and photon emission angle over a wide range of the relative photon energy kiT o up to k/To=0.83. The measured cross sections are compared with results of Bethe-Heitler and Elwert-Haug calculations

The production of bremsstrahlung by transversely polarized electrons shows an azimuthal asymmetry. Measurements and calculations of this effect are presented. They indicate that the partial waves method -in the form used by Tseng and Pratt is suitable to describe this polarization correlation.

Elastic Scattering of 100 to 150 keV Electrons The angular dependence of elastic scattering of 100 to 150 keV electrons has been measured for scattering angles of 5 ~ to 165 ~ . The atomic numbers of the scattering atoms were 6 and 79. Within the experimental errors (few per cent) we found agreement with the results of the calculations of Lin.
