摘要
在活动星系核吸收光谱中存在着一种重要的吸收特征—铁元素的M壳层不可分辨跃迁系吸收谱,认识这种特征对于活动星系核区的物理性质的研究具有重要的意义.利用细致谱线模型,对实验室中获得的吸收谱进行了理论计算和分析,较好地重现了实验结果中主要的吸收结构,同时计算了温度为10—50 eV的预测吸收谱,用于活动星系核光谱的研究.
M-shell unresolved transition array of iron is an important diagnostic tool of the X-ray spectrum of active galactic nuclei. This array is measured in the laboratory, and compared with several theoretical models. In the present paper, we introduce a detailed line counting model. With this model, we simulate the experimental spectra, and the comparison shows a good agreement. We also calculate the absorption spectra in a temperature range of 10-50 eV.
