摘要:

共振非弹性X射线散射(RIXS)已成为研究凝聚态物质电子结构的有力工具。虽然许多RIXS特征的线宽很窄,但实验加宽往往会妨碍光谱特征的识别。在这里,我们表明,最大熵技术可以成功地应用于RIXS光谱的反卷积,改善了损失功能的解释,而不会严重增加噪声比。

英文摘要:

Resonant inelastic x-ray scattering (RIXS) has become a powerful tool in the study of the electronic structure of condensed matter. Although the linewidths of many RIXS features are narrow, the experimental broadening can often hamper the identification of spectral features. Here, we show that the Maximum Entropy technique can successfully be applied in the deconvolution of RIXS spectra, improving the interpretation of the loss features without a severe increase in the noise ratio.
