Abstract The Larmor-precession frequencies for197Hg in Fe have been determined to beω L = 1291 ±25 MHz at 293 K andω L = 1334±25 MHz at 105 K. For199Hg in Feω L =1372±50 MHz has been measured at 293 K. The half-lives of the 5/2− states in197Hg and199Hg have been remeasured asT 1/2(197Hg)=8.1±0.16 nsec andT 1/2(199Hg)=2.45±0.05 ns, respectively. The magnetic moment of the 5/2− 158keV state in199Hg was redetermined by the integral perturbed angular correlation method in an external magnetic field of 47kG asμ(5/2 − ) = 0.905±0.091 nm. With this new value consistency for the magnetic hyperfine fields at Hg in Fe measured with the TDPAC-method and with the NMR/ON-method is obtained. This fact is used to determine theg-factors of the 5/2− states in197Hg and199Hg more precisely fromω L -values given above:g(197Hg)=0.342(6);g(199Hg)=0.352(13). The magnetic moments of the first excited 2+ states in198–204Hg isotopes which rely on calibrations with the199Hg-g-factor, are revised.
