Isotope Shift and Hyperfine Structure Measurements in Xe II in a Laser-Ion Beam Experiment

Hyperfine structure of the transition 5d4D7/2-6p4P05/2 in Xe II is measured for the isotopes 129,131Xe, and h.f.s. coupling constants A and B are evaluated for the 6p4P05/2 level. Isotope shifts in the same transition are measured for 128,129,130,131,134,136Xe relative to 132Xe utilizing Lambdip technique in a beam-laser experiment. The field shifts are evaluated yielding relative changes δ ⟨r2⟩ of mean-square charge radii.
