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 (1)Ci (137)Cs source and a 3''x3'' 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.
本研究的目的是测量玻璃基板上钛涂层的康普顿轮廓，并将其与基于哈特里-福克模型由希尔曼和斯基尔曼程序计算出的轮廓进行比较。实验康普顿轮廓是使用来自1居里（137）铯源的661.7keV伽马射线和一个3英寸×3英寸碘化钠（铊）探测器获得的。对钛的实验、理论和展开后的康普顿轮廓进行了比较。结果表明，与其他两者相比，实验康普顿轮廓的宽度。这种差异主要可归因于多普勒展宽效应、电子的最终量子态，部分也归因于理论模型中采用的近似方法。
