In this study, seven alloys with a nominal composition of (CuO) M (M = Fe, Co, Ni, Cu, Zn, Y, and Nb wt%) were produced via the powder mixed method. Alloys and pure metals were excited with 59.54 keV photon energy emitted from Am-241 radioactive source at 25°, 35°, 45°, 55°, 65°, 75' and 85° scattering angles. The spectra of the coherent/Compton peaks were obtained by Si(Li) detector. First of all, chemical shift, (ΔE) peak energies, (E) asymmetry index (A) and full width half maximum (FWHM) values were found in the Compton/Coherent scattering spectra obtained depending on the scattering angle and the chemical environment of the transition metals. Then the ratios of the Coherent/Compton scattering differential cross-section (dσ/dσ) were obtained experimentally. The experimental dσ/dσ ratios of the selected 3d-4d transition metals were found to be compatible with the data in the literature. Asymmetry and chemical shifts were observed in almost all samples, especially in Compton peaks, with increasing scattering angles. The chemical shifts of Compton and Coherent peaks of the alloys were found in the range of 1-932 eV. The experimental dσ/dσ ratios for the alloys obtained by adding Fe, Co, Ni, Cu, Zn, Y, and Nb to CuO were found as 0.697, 0.689 0.678, 0.698, 0.736, 0.755, 0.798, 0.835 at 45° scattering angle, respectively. It has been determined that the experimental dσ/dσ ratio for each alloy increases with increasing atomic number, while it decreases with increasing scattering angle.
在这项研究中，通过粉末混合法制备了七种名义成分为（CuO）M（M = Fe、Co、Ni、Cu、Zn、Y 和 Nb wt%）的合金。在 25°、35°、45°、55°、65°、75°和 85°散射角下，用 Am-241 放射性源发射的 59.54keV 光子能量激发合金和纯金属。通过 Si(Li)探测器获得相干/康普顿峰的光谱。首先，根据散射角和过渡金属的化学环境，在获得的康普顿/相干散射光谱中找到了化学位移（ΔE）峰能量、（E）不对称指数（A）和半峰全宽（FWHM）值。然后，实验获得了相干/康普顿散射微分截面（dσ/dσ）的比值。选定的 3d-4d 过渡金属的实验 dσ/dσ 比值与文献中的数据相吻合。随着散射角的增加，几乎所有样品中都观察到不对称和化学位移，特别是在康普顿峰中。发现合金的康普顿和相干峰的化学位移在 1-932eV 的范围内。在 45°散射角下，向 CuO 中添加 Fe、Co、Ni、Cu、Zn、Y 和 Nb 得到的合金的实验 dσ/dσ 比值分别为 0.697、0.689、0.678、0.698、0.736、0.755、0.798、0.835。确定每个合金的实验 dσ/dσ 比值随原子序数的增加而增加，随散射角的增加而减小。
