A deconvolutional method for preprocessing powder diffraction data has been improved. The cumulants of instrumental aberration functions of Bragg-Brentano (Parrish) diffractometer calculated up to the fourth order are presented. The treatments of axial-divergence aberration and the effective spectroscopic profile of the source X-ray have been simplified from those used in previous methods. The current method has been applied to powder diffraction data collected with a Cu-target X-ray tube, used over 20 years, and a Ni-foil Kβ filter.

将反卷积处理应用于使用带有污染的 Cu 靶和 Ni 过滤器的 Bragg-Brentano 衍射仪收集的粉末衍射数据

改进了预处理粉末衍射数据的反卷积方法。给出了布拉格-布伦塔诺(Parrish)衍射仪仪器像差函数的累积量,计算到四阶。轴向发散像差的处理和源 X 射线的有效光谱轮廓已从以前的方法中使用的那些简化。目前的方法已应用于使用已使用 20 多年的铜靶 X 射线管和镍箔 K 收集的粉末衍射数据。β筛选。
