Abstract An unexpectedly small hyperfine anomaly ϵ = (−11 ± 12) × 10 − is found between the 27.8 keV (5/2 + ) and the ground state ( 7 2 + ) of 129 I. A single-particle shell-model calculation yields a much larger anomaly, but mixing-in excited-state configurations reduces the calculated anomaly considerably.
