Abstract
The Compton profiles of aluminium and iron have been measured with 662 keV γ-radiation from a caesium-137 source. The experiment was conceived as a feasibility study of high-energy, γ-ray Compton profile measurements intended for future application to materials of high atomic number. Instrument calibration and data corrections for the high-energy experiment are discussed, together with its advantages and limitations. The data are compared with published theoretical Compton profiles of aluminium and iron, and with published measurements made with the 60 keV γ-radiation of americium-241.
