X-ray missions with microcalorimeter technology will resolve spectral features with unprecedented detail. In this work, we improve the H-like Kα energies for elements between 6≤Z≤30 for the release version of the spectral simulation code Cloudy to match laboratory energies. We update the ionization potential (I _ion) for these elements and add a fourth-order polynomial to the level energy difference. This brings the release version of Cloudy into a near-perfect agreement with NIST. The updated energies are ∼15–4000 times more precise than that of the current release version of Cloudy (C17.02). These new changes will be a part of the next update to the release version, C17.03.

采用微量热计技术的 X 射线任务将以前所未有的细节解析光谱特征。在这项工作中，我们为光谱模拟代码 Cloudy 的发布版本改进了6≤ Z ≤30 之间元素的 H 类 K α能量，以匹配实验室能量。我们更新这些元素的电离势 ( I _ion )，并将四阶多项式添加到能级能差中。这使 Cloudy 的发布版本与 NIST 达成了近乎完美的协议。更新后的能量比 Cloudy 的当前版本 (C17.02) 精确 15-4000 倍。这些新更改将成为发布版本 C17.03 下一次更新的一部分。
