[en] 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 300, 450, 600, 900, and 1350. 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
