摘要：扩展的X射线吸收精细结构的计算通过处理弹出的光电子作为一个球面波，在晶格中扩展，并部分地被邻居的吸收原子散射。相邻原子被视为点散射体，总散射波由每个原子散射的波求和。精细结构由初始K态和最终光电子态之间的偶极跃迁矩阵确定。计算结果与实验数据相比是令人满意的。（作者）
Abstract : The extended x-ray absorption fine structure is calculated by treating the ejected photoelectron as a spherical wave which expands in the lattice and is partially scattered by neighbors of the absorbing atom. The neighboring atoms are treated as point scatterers and the total scattered wave is summed from the waves scattered by each atom. The fine structure is determined from the dipole transition matrix between the initial K-state and the final photoelectron state. Calculations compare favorably with experimental data. (Author)
