Spectrum analysis of CrII

We have made new observations of the spectrum of singly ionized chromium (CrII) in the region 2850-37900{AA} with the National Institute of Standards and Technology 2m Fourier...我们借助美国国家标准与技术研究院（National Institute of Standards and Technology）的2米傅里叶光谱装置，在2850–37900埃（Å）波段范围内，对单电离铬（CrII）的光谱开展了全新观测。
