Theoretical and experimental analysis of titanium Compton profile using 137Cs

Abstract: The objective of this study is to measure the Compton profile of a titanium coating on a glass substrate, comparing it with a profile computed by the Hillman and Skilman program based on the Hartree–Fock model. The experimental Compton profile was obtained using 661.7keV gamma-rays from a 1Ci 137Cs source and a 3″×3″ NaI(Tl) detector. The experimental, theoretical and unfolded Compton profiles of titanium have been compared. The results illustrate the breadth of experimental Compton profile in comparison with the two others. This difference can be mainly attributed to the Doppler broadening effect, the final quantum state of the electron and partly by the approximations implemented in the theoretical model.
