Abstract
The Compton profiles of aluminium and germanium have been measured with 412 keV gamma-radiation from a 198Au source. The resolution obtained in this experiment improves on previous Compton scattering studies of electron momentum distributions made with lower energy gamma-ray sources. The results for aluminium are in good agreement with other Compton profile measurements, and with theory, thus establishing the validity of the technique. The advantages and disadvantages of using this source are discussed, particularly for heavier materials such as germanium.
