It follows that two experiments of hyperfine structure of atomic energy level which are called magnetic resonamce experiment and co-line expression beam interative experiment.
介绍了研究原子能级超精细结构的两个实验：磁共振实验、共线快离子束相互作用实验。

This article is aimed at introducing the generation principle of fine structure and hyperfine structure of atomic energy level, with its experimental result improved, designed and illustrated.
The isotope shifts, hyperfine structure, spontaneous emission branch ratio of the first excited level and Doppler width of the atom vapor beam were measured using laser induced fluorescence.
