    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 Spin-echo measurements on183W were performed with dilute alloys of W (0.1, 0.25, 0.5 and 1 at %) in Fe. The result for the hyperfine field:B 4.2K hf =(−)62 · 54 (3) T agrees with the old data of Kontani and Itoh, but the accuracy is much better. The giant hyperfine anomaly of183W with respect to184W2+ observed by Alzner et al. is thus confirmed and the errors are reduced to:184W2+Δ183Wg=+0.150(31). This is the first case of a very large hyperfine anomaly in electronic hyperfine fields which is not caused by the pathological cancellation of orbital and spin magnetism in jackknifep 1/2 ord 3/2 single proton configurations. A detailed discussion shows that the large hyperfine anomaly may be related to the anomalously small magnetic dipole moment of183W. Our result should stimulate further theoretical work with the aim to understand this magnetic moment as well as the giant hyperfine anomaly.
