我们将 Mn K{beta}(3p{yields}1s) 发射数据呈现为激发和发射的宽能量范围内的等高线图。结果表明，通过根据 Kramers-Heisenberg 方程导出的公式分析数据，可以推导出自旋偏振 X 射线吸收近边缘结构 (SPXANES)。由此获得的SPXANES光谱与传统方法的光谱有很大不同，但与洪德规则的预期一致，并且总体光谱形状以及峰位置与理论计算吻合良好。
We present Mn K{beta}(3p{yields}1s) emission data as a contour map over wide energy ranges in both excitation and emission. It is demonstrated that spin-polarized x-ray absorption near edge structure (SPXANES) can be deduced by analyzing the data in terms of a formula derived from the Kramers-Heisenberg equation. The SPXANES spectra thus obtained are considerably different from those by conventional method, but are consistent with an anticipation from Hund's rule, and the overall spectral shapes as well as peak positions agree well with a theoretical calculation.
