In this paper, we present a reanalysis of the silicon He- $\mathrm{\alpha}$ X-ray spectrum emission in Fujioka et al.’s 2009 photoionization experiment. The computations were performed with our radiative-collisional code, RCF. The central ingredients of our computations are accurate atomic data, inclusion of satellite lines from doubly excited states and accounting for the reabsorption of the emitted photons on their way to the spectrometer. With all these elements included, the simulated spectrum turns out to be in good agreement with the experimental spectrum.

光电离实验中硅 He-α 线的发射机制

在本文中，我们对硅 He- $\mathrm{\alpha}$ 藤冈的 X 射线光谱发射等人. 的 2009 年光电离实验。计算是使用我们的辐射碰撞代码 RCF 进行的。我们计算的核心要素是准确的原子数据，包括来自双激发态的卫星线，以及发射光子在到达光谱仪的途中的再吸收。包含所有这些元素后，模拟光谱与实验光谱非常吻合。
