Abstract

The difference in the mean-square nuclear charge radius of xenon isotopes was measured utilizing a method based on extreme ultraviolet spectroscopy of highly charged Na-like ions. The isotope shift of the Na-like D1 (3s 2S1/2 − 3p 2P1/2) transition between the 124Xe and 136Xe isotopes was experimentally determined using the electron-beam ion-trap facility at the National Institute of Standards and Technology. The mass-shift and the field-shift coefficients were calculated with enhanced precision by the relativistic many- body perturbation theory and multiconfiguration Dirac-Hartree-Fock method. The mean-square nuclear charge radius difference was found to be δr2136,124 = 0.269(42) fm2. Our result has smaller uncertainty than previous experimental results and agrees with the literature values.charge radius difference was determined to be ä136, 124 = 0.269(0.042) fm2. Our result agrees with previous experimental results and shows agreement with a recommended value obtained from a detailed compilation and evaluation of experimental nuclear charge radii [I. Angeli and K. P. Marinova, At. Data and Nucl. Data Tables 99, 69-95 (2013)].
