|a The isotope shifts and hyperfine structure splittings of nine stable xenon isotopes in the mass range from 124 to 136 have been measured using the electronic transition 5d⁴D[subscript 7/2] - 6p⁴P⁰ [subscript 5/2] in the Xe II spectrum. The method of collinear fast ion beam laser spectroscopy has been utilized to achieve Doppler-free resolution and a high sensitivity. An ion beam apparatus consisting of an Einzel lens, a switch magnet and two electrostatic quadrupole triplets was designed to transport the ions from an on-line ion source through the TRISTAN isotope separator to the interaction region where, at resonance, the fluorescence signal was observed. A line shape analysis, based on an asymmetrical exponential function, was developed to interpret the recorded data. Changes in the mean square charge radii δ(r²)[superscript AA'] for the chain of stable xenon isotopes were extracted from the measured isotope shifts. The hyperfine structure constants A and B, the nuclear magnetic dipole moment μ[subscript I], and the electric quadrupole moment Q were evaluated from the splittings. The effect of the nuclear deformation below the magic number 82 is discussed in the two-parameter liquid drop model and the three-parameter droplet model. A comparison of the δ(r²)[superscript AA'] of Xe with those of the neighboring elements of Cs and Ba is made.
