标题： Benchmarking atomic data for astrophysics: a first look at the soft X-ray lines

摘要： 这里使用了软X射线区域的最佳太阳和实验室光谱，通过比较观测波长与预测波长以及校准的太阳辐照度，对这一波长区域进行了初步基准测试。 该基准测试聚焦于Fe IX - Fe XIV离子，我们最近计算了相关的原子数据，但还有一些其他离子也被进行了基准测试。 铁离子主导了软X射线，但之前由于n=4 -> n=3跃迁产生的最强软X射线谱线大部分未被识别。 所有最强跃迁在这里都被识别出来，特别是从核心激发态水平（3s 3p^l 4s，l=5,4,3,2,1分别对应Fe X, Fe XI, Fe XII, Fe XIII和Fe XIV）的衰减，这些是这些离子产生的最强软X射线跃迁。 提出了许多新的识别结果，其中一些仅是暂时性的。 在软X射线和EUV（n=3 -> n=3）跃迁的太阳辐照度方面发现了良好的一致性，证实了新大规模计算的可靠性。 其中一些新的原子数据和识别结果对于太阳动力学天文台（SDO）大气成像组件（AIA）94 A波段尤为重要。 显示英文摘要

摘要： A collection of the best solar and laboratory spectra in the soft X-rays is used here to perform a preliminary benchmark in this wavelength region, by comparing observed vs. predicted wavelengths and calibrated solar irradiances. The benchmark focuses on the Fe IX - Fe XIV ions,for which we have recently calculated the relevant atomic data, however a few other ions have also been benchmarked. The iron ions are dominating the soft X-rays, however a large fraction of the strongest soft X-ray lines due to n=4 -> n=3 transitions were previously unidentified. The strongest transitions are all identified here, in particular the decays from the core-excited levels (3s 3p^l 4s, l=$ 5,4,3,2,1 for Fe X, Fe XI, Fe XII, Fe XIII, and Fe XIV respectively) which are the strongest soft X-ray transitions from these ions. Many new identifications are proposed, some only tentatively. Good agreement in terms of solar irradiances between the soft X-ray and EUV (n=3 -> n=3) transitions is found, confirming the reliability of the new large-scale calculations. Some of the new atomic data and identifications are particularly important for the Solar Dynamic Observatory (SDO) Atmospheric Imaging Assembly (AIA) 94 A band.
