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(2)S(1/2) - 3(P)(2)P(1/2)) transition between the Xe-124 and Xe-136 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 delta < r(2)>(136,124) = 0.269(42) fm(2). Our result has smaller uncertainty than previous experimental results and agrees with the literature values.
