Differential Cross-Section Measurements of Thin-Target Bremsstrahlung Produced by 2.7- to 9.7-Mev Electrons

Abstract

The electron beam removed from a 50-Mev betatron and a total absorption scintillation spectrometer containing a sodium iodide crystal 5 in. in diameter and 9 in. long were used for the measurement of brems-strahlung cross sections that are differential in photon energy and angle. Thin targets of beryllium, aluminum, and gold were bombarded by electrons with kinetic energies of 2.72, 4.54, and 9.66 Mev. The bremsstrahlung spectra from thick tungsten targets were also studied.
