    Notes: Abstract A mini transmissionγ-ray Compton polarimeter was developed for the measurement of the sign of magnetic moments of radioactive nuclei with low-temperature nuclear orientation. The signs of the magnetic moments of the following isotopes were determined:193Os [μ=+0.7297(16)μ N];191m Ir [μ=+6.20(9)μ N];192Ir [μ=+1.924(10)μ N];194Ir [μ=+0.39(1)μ N];195m Pt [μ=−0.605(15)μ N].

    Notes: Abstract The magnetic and electric hyperfine splitting frequencies ¦gμ N B HF/h¦ ande 2 qQ/h of the 5/2−1/2[541] ground state of 14h 185Ir in Ni were measured with nuclear magnetic resonance on oriented nuclei to be 360.8(7) MHz and +6.7(2.0) MHz, respectively. The ground state magnetic dipole moment and electric quadrupole moment of185Ir are deduced to be ¦μ¦=2.601 (14)μ N andQ=−1.9(5)b, taking values for the hyperfine field and electric field gradient of BHF=−454.9 (2.3) kG and eq=−0.151(4) × 1017 V/cm2, respectively. The negative quadrupole moment is in agreement with nuclear-orientation data and proves again theI π K=5/2− 1/2 ground state configuration.

    Notes: 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).

    Notes: Abstract The magnetic hyperfine splitting frequenciesν M=¦gμ NBHF/h.¦ of the 11/2− isomeric states129m Xe (T1/2=8.9d) and131mXe (T1/2=11.8d) in Fe were measured with nuclear magnetic resonance on oriented nuclei at temperatures of 10–15 mK as 188.0(1) MHz and 209.8(1) MHz, respectively, the samples being prepared with the technique of recoil implantation after (α, x n) reactions. The magnetic moments of129m Xe and131m Xe are deduced to be (−)0.8914(6)μ N and (−)0.9943(6)μ N, respectively. The missing γ-anisotropies for allγ-transitions following the decay of 36.4d 127Xe indicateI=1/2 for the ground state spin of127Xe.
