The nuclear decay of the 5/2+ 139 keV state to the 3/2+ ground state was observed in muonic193Ir. The hyperfine splitting of the 3/2+ state and 5/2+ state was determined to be 640±100 eV and 1280±160 eV, respectively. The ground state splitting is about twice that of a point nucleus, an anomaly never observed this large. This is mainly due to the different radial distribution of spin and orbital magnetization of a d3/2 proton configuration for which these contributions nearly cancel to zero in the magnetic moment. But calculations including configuration mixing and coupling to a vibrating or a deformed core show deviations. The groundstate anomaly is in line with that observed by the Mossbauer technique.
