Hyperfine structure of the 5p(5)(2)P(3/2) 5d[7/2]( degrees )(4), (2)P(3/2) 5d[3/2]( degrees )(2), and (2)P(3/2) 6p[5/2](3) levels in Cs II measured with beam-laser technique.

The hyperfine structures of the 5p(5)(2)P(3/2) 5d7/2(4), (2)P(3/2) 5d3/2(2), and (2)P(3/2) 6p5/2 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.
