Abstract

An interferometric method is used to improve the accuracy of the 7S−7P transition frequencies of three francium isotopes by 1 order of magnitude. The deduced isotope shifts for Fr209–211 confirm the ISOLDE data. The frequency of the D2 transition of Fr212—the accepted reference for all Fr isotope shifts—is revised, and a significant difference with the ISOLDE value is found. Our results will be a benchmark for the accuracy of the theory of Fr energy levels, a necessary step to investigate fundamental symmetries.
