- Аннотация: The probability of the E0 transition between the components of the magnetic hyperfine (MHF) structure of the ground 5/2+(0.0) and the low-energy 3/2+(7.8 ± 0.5 eV) levels is calculated in the muonic atom (μ−1S1/2 229Th)∗. [The MHF splitting taking into account the Bohr-Weisscopf effect and the mixing of the F = 2 sublevels was found earlier in the paper E. V. Tkalya, Phys. Rev. A 94, 012510 (2016)] The mean-square charge radius of the isomeric state in 229Th is estimated from the data for the 3/2+(0.0) state of the 223,227Ra nuclei and the 5/2+(0.0) state of the 221,229Ra nuclei. The resulting E0 transition probability is found to be anomalously small in comparison to the known value for the 0+ → 0+ nuclear transitions, which is explained by the similarity between the mean-square charge radii of the ground and low-energy isomeric states in 229Th.
