Collinear laser-ion beam determination of hfs in Cs II

Hyperfine structure in the 576 nm line of Pr II by collinear fast-ion-beam laser spectroscopy

“…Dufay and Gaillard (1977) initiated the in-flight Lamb-dip technique for HFS measurements. Bengtson et al (1980) used collinear ion-beam laser spectroscopy for HFS measurement in Cs II. Berrah-Mansour et al (1989) measured the HFS of Sc II by using an RF-laser double-resonance method.…”
