Theg-factor of the 181 keV level of99Tc and hyperfine fields of Tc in Fe,Co, Ni

Theg-factor of the 181 keV-level of⁹⁹Tc has been redetermined by the spin rotation method. Measurements with polycrystalline sources of Tc in Fe, Co, and Ni yielded values of the hyperfine fields at the Tc nucleus. $$begin{gathered} g = + 1.310(25) hfill H_{hf} (Tc{mathbf{ }}in{mathbf{ }}Fe) = ( - )290(15)kOe hfill H_{hf} (Tc{mathbf{ }}in{mathbf{ }}Co) = ( - )170(5)kOe hfill H_{hf} (Tc{mathbf{ }}in{mathbf{ }}Ni) = - 47.8(1.5)kOe. hfill end{gathered} $$
