Theoretical isotope shifts in neutral barium

Abstract

The present work deals with a set of problems in isotope shifts of neutral barium spectral lines. Some well known transitions ($6s^2{}^1{S}_0-6s6p{}^{1,3}{P}_1^o$ and $6s^2{}^1{S}_0-6p^2{}^3{P}_0$) are first investigated. Values of the changes in the nuclear mean-square charge radius are deduced from the available experimental isotope shifts using our ab initio electronic factors. The three sets $\{\delta ⟨r^2{⟩}^{A,A^{\prime }}\}$ obtained from these lines are consistent with each other. The combination of the available nuclear mean-square radii with our electronic factors for the $6s5d{}^3{D}_{1,2}-6s6p{}^1{P}_1^o$ transitions produces isotope shift values in conflict with the laser spectroscopy measurements of Dammalapati et al. (Eur. Phys. J. D 53, 1 (2009)).
