Hyperfine structures and isotope shifts of the 5d4D7/2→6p4P5/20 transition in Xenon ions
Collinear fast beam-laser spectroscopy has been performed on metastable 5d4D7/2 Xenon ions. Hyperfine structure constants for the 6p4P5/20 level have been derived for129Xe:A=−1,634.9±0.9 MHz and131Xe:A=485.3±0.3 MHz andB=−116.5±2.0MHz. Changes in mean squared nuclear charge radii are derived from the measured isotope shifts.
