本文介绍了一种简单而相对精确的测定消光距离和反常吸收系数的方法。该方法使用的测量上得到的商业扫描透射电子显微镜（STEM）装有一个专门设计的聚光镜孔径会聚束衍射图案。在铜中的各种反射得到的结果进行了比较，从文献中的理论值。
A simple and relatively accurate technique for determining extinction distance ζgand anomalous absorption coefficient ζg/ζg′ is described. The method uses measurements made on convergent beam diffraction patterns obtained with a commercial scanning transmission electron microscope (STEM) fitted with a specially designed condenser aperture. Results obtained for various reflections in copper are compared with theoretical values taken from the literature.
