在角分辨光电发射光谱学中，在各种设置中映射光电子分布的功能
Functions to map photoelectron distributions in a variety of setups in angle-resolved photoemission spectroscopy
摘要：
角分辨光电子能谱中获得的光电子分布可以映射到晶体中布洛赫电子的能量-动量空间。映射函数$f$的显式形式取决于装置的配置以及光电子分析仪的类型。我们表明，存在的解析形式的$f^{\text{-}1}$是保证在各种设置。这种变化包括分析器配备有光电子偏转器的情况。因此，我们提供了一个示范性的映射程序实现的算法，利用$f$和$f^{\text{-}1}$。映射方法也可用于其他光谱方法，如动量分辨电子能量损失光谱。
英文摘要：
The distribution of photoelectrons acquired in angle-resolved photoemission spectroscopy can be mapped onto energy-momentum space of the Bloch electrons in the crystal. The explicit forms of the mapping function $f$ depend on the configuration of the apparatus as well as on the type of the photoelectron analyzer. We show that the existence of the analytic forms of $f^{\text{-}1}$ is guaranteed in a variety of setups. The variety includes the case when the analyzer is equipped with a photoelectron deflector. Thereby, we provide a demonstrative mapping program implemented by an algorithm that utilizes both $f$ and $f^{\text{-}1}$. The mapping methodology is also usable in other spectroscopic methods such as momentum-resolved electron-energy loss spectroscopy.
