Experimental data are presented for the absolute cross section for atomic-field bremsstrahlung produced by 50-, 100-, and 140-keV electron bombardment of thin targets of aluminum, copper, silver, and gold at photon angles of 30°, 45°, 60°, 90°, and 135°. The data are compared with the theory of Pratt et al. and generally found to be in very good agreement, although there are some small discrepancies between theory and experiment.
