摘要：
All available experimental data on isotope shifts and absolute frequency measurements in the optical spectra of Ca I and Ca II are re-evaluated, and from them complete tables of isotope shifts and energy levels of all Ca isotopes from 36 to 52 are derived. A global least-squares fitting of these data was performed. From this fit, the field and mass shift constants for all involved transitions and energy levels were derived along with improved values for differences of mean squared nuclear charge radii.
