近年来,应用激光技术光化学分离铀同位素已成为学术界瞩目的课题。激光分离铀同位素需要有关铀原子光谱的完整数据。为了提供铀同位素光谱间重叠小的锐的吸收谱线,提高原子法激光分离铀同位素的分离效率,必需研究有关铀原子光谱的同位素位移,同位素谱线强度比,超精细结构,激发态寿命,吸收截面和电离截面等许多光谱参数。这是确定分离方案的重要依据。但是,由于铀的高温腐蚀性,放射性,及光谱的复杂性,给铀原子光谱研究带来很大困难。现有的光谱数据多半还是最初用经典光学的
In recent years, the application of laser photochemical separation of uranium isotopes has become a subject of academic attention. Laser separation of uranium isotopes requires complete data on the uranium atomic spectra. In order to provide a sharp and sharp absorption line overlapped between uranium isotope spectra and improve the separation efficiency of uranium isotopes by atomic laser, it is necessary to study isotope shifts of isotope spectra, uranium atomic spectral intensity ratio, hyperfine structure, excited state lifetime, Absorption section and ionization section and many other spectral parameters. This is an important basis for determining the separation scheme. However, due to the high temperature corrosiveness of uranium, radioactivity and the complexity of the spectrum, it is very difficult to study the spectroscopy of uranium atoms. Most of the existing spectral data is still originally used in classical optics
