Hyperfine structure of the 5p 5 P2 3/2 5d[7/2]4∘,P2 3/2 5d[3/2]2∘, and 2 P 3/2 6p[5/2] 3 levels in Cs ii measured with beam-laser technique

The hyperfine structures of the 5p5 P23/2 5d[7/2]4∘,P23/2 5d[3/2]2∘, and 2P3/2 6p[5/2]3 levels in Cs ii have been determined in a laser–ion-beam experiment. The hyperfine-structure constants A and B for the levels have been evaluated.
