“…The measurements yield no unambiguous interpretation of the origin of the hyperfine field distribution, and particularly of the Lorentzian shape for which the results were best fitted, as is seen in Fig. la, b, present work by a distortion of the host lattice in the immediate vicinity of the introduced impurity atoms, particularly in substances with large magnetostriction such as nickel as is pointed out in [9]. The observed field distribution width FWHM = = 22% for T a nuclei in the Ni lattice is compared with FWHM = 11 yo given by Winkler et al [9] for Tc nuclei in the Nilattice.…”

The hyperfine field a t Ta nuclei diffused into a nickel foil was studied by the PAC method both with and without an external polarizing magnetic field. The value Hhf = (-82.6 f 1.1) kG is smaller than the reported one of 90 kG, which could be explained by the large field distribution observed. For assumed Lorentzian shape of the field distribution FWHM Es wurde das Hyperfeinfeld an Ta-Kernen, die in eine Nickelschicht eindiffundiert wurden, mittels der PAC-Methode ohne Feld und mit BuBerem, polarisierendem Magnetfeld untersucht. Der Wert Hhf = (-82,6 1 , l ) kG ist kleiner als der berichtete von 90 kG, was durch die groBe beobachtete Feldverteilung erklart werden kann. Fur eine angenommene Lorentzform der Feldverteilung ergibt sich FWHM (6) = 22%.(6) = 22%.

“…The hyperfine field of Tc in Fe, BFI v (TcF_ee), has been the subject of many investigations [1][2][3][4][5][6], with partly contradicting results. Winkler et al [1] performed a TDPAC measurement on 99TcFe, from which they derived BHv (TcFe) = ( -)290(15) kG (at T-= 298 K).…”

“…Winkler et al [1] performed a TDPAC measurement on 99TcFe, from which they derived BHv (TcFe) = ( -)290(15) kG (at T-= 298 K). For that purpose they measured additionally the g-factor of the 181 keV state of 99Tc with PAC on 99Tc Cu in an external magnetic field [B~x t = 29.80(15) kG], with the result g= 1.310(25).…”

Abstract. We report measurements of nuclear magnetic resonance on oriented nuclei (NMR-ON) on 94Tc (U = 7 +, T m = 4.9 h), 95Tc (In = 9/2 +, T~/2 = 20 h) and 96Tc (U=7 +, T~/2= 4.3 d ) in Fe and on 95Tc and 96Tc 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 Bex t up to 2.0 T. In addition, TDPAC measurements were performed on 99TcFe at T-300 K and 13 K. The T= 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 of 93Tc, 94Tc, 95Tc, 96Tc and 99Tc(E=181keV; P=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(i7).
