High-resolution collinear laser spectroscopy has been performed on singly charged ions of U at the IGISOL facility of the Accelerator Laboratory, University of Jyväskylä, in Finland. Ten ionic transitions from the and ground and first excited states were measured in the 300 nm wavelength range, improving the precision of the hyperfine parameters of the lower states in addition to providing newly measured values for the upper levels. Isotope shifts of the analyzed transitions are also reported for U with respect to U.
在芬兰于韦斯屈莱大学加速器实验室的IGISOL设施上，对铀的单电荷离子进行了高分辨率共线激光光谱研究。在300纳米波长范围内测量了来自基态和第一激发态的10个离子跃迁，除了为高能级提供新的测量值外，还提高了低能级超精细参数的精度。还报告了相对于铀-238的铀-235分析跃迁的同位素位移。
