The Fe 2p spectrum has a very complex peak structure and a very strong background. Based on the comparison of the spectra for iron film with varying thicknesses, an experimental multiple‐peak structure for the metallic Fe 2p spectrum is proposed. The analysis required the use of state‐of‐the‐art background modeling (including the active approach) and peak‐fitting methods (including the simultaneous fitting method). A key aspect that allowed for this analysis is that the peak components are the same for various Fe film thicknesses, but with varying relative intensities. The early stages of oxidation are analyzed. The angular dependence of the peak components is also discussed.

Fe 2p金属的光发射光谱的自洽多峰结构与膜厚度的关系

Fe 2 p光谱具有非常复杂的峰结构和非常强的背景。在对不同厚度的铁膜光谱进行比较的基础上，提出了金属Fe 2 p光谱的实验多峰结构。分析需要使用最新的背景建模（包括主动方法）和峰拟合方法（包括同时拟合方法）。允许进行此分析的一个关键方面是，各种Fe膜厚度的峰成分相同，但相对强度却有所不同。分析了氧化的早期阶段。还讨论了峰值分量的角度依赖性。
