Abstract We report measurements of nuclear magnetic resonance on oriented nuclei (NMR-ON) on94Tc (Iπ=7+,T 1/2=4.9 h),95Tc (I π=9/2+,T 1/2=20 h) and96Tc (I π=7+,T 1/2=4.3 d) in Fe and on95Tc and96Tc in Ni. In order to elucidate the discrepancies on the hyperfine field of TcFe in the literature, the resonances were measured with high precision as a function of the external magnetic field Bext up to 2.0 T. In addition, TDPAC measurements were performed on99TcFe at T=300 K and 13 K. TheT=0 K hyperfine fields of Tc in Fe and Ni were determined to be −314(3) kG and −51.8(5) kG, respectively. The g-factors of93Tc,94Tc,95Tc,96Tc and99Tc(E=181 keV;I π=5/2+) are redetermined as g(93Tc)=1.405(14), g(94Tc)=0.731(7),g(95Tc)=1.321(13), g(96Tc)=0.727(7), g(99Tc)=1.390(17).
