N1  - The authors thank V. V. Flambaum and V. A. Dzuba for stimulating discussions and providing the corrected lifetimes, and M. Block, Ch. Mokry, and J. Runke for providing the actinium sample. We gratefully acknowledge discussions with R. Beerwerth and S. Fritzsche on the theory of the actinium hyperfine structure. The work was supported by the German Federal Ministry of Education and Research under the Projects No. 05P15UMCIA, No. 05P18UMCIA. D. B. was supported in part by the DFG Project ID 390831469: EXC 2118 ( PRISMA+Cluster of Excellence).
