Compton profile measurement of Tungsten polycrystalline sample has been performed with 662 KeV γ-radiation from a cesium-137 source scattered at 900. The Spectrometer calibration and data corrections for the high energy experiment are discussed. The data are compared with the augmented-plane-wave (APW) band theoretical Compton profile of Tungsten. Theoretical predictions show the band theory overestimates the momentum density at low momenta and underestimates it at intermediate momenta. The discrepancies between experiment and theory were attributed to some non-local exchange-correlation effects and the spin-orbital interaction effect which were neglected in the theoretical calculation.

Keywords: high energy gamma-ray spectroscopy, methods and technologies, characterization techniques, modelling and materials theory, compton scattering, and detection techniques
