The following g-factors have been derived from time integral measurements of 7-7 angular correlations in the static magnetic hyperfine field of magnetized gadolinium metal probes:= +0.310(19) g(6 +) = + 0.25(21) 4 + g~ 3,1511 keV)= +0.809(27) 158Gd: g(4 +) = +0.409(15).The 5.35 d 156Tb sources were produced by the reaction t 56Gd(d ' 2 n) 156Tb in our cyclotron. A carrier-free 150 y 15STb source was obtained from ISOLDE/CERN. In comparison with the precisely known g-factors of the 2+ states, g(2+, 156Gd)= +0.386(4) and g(21 +, 158Gd)=0.381(4), we observe a large reduction for the 156Gd 4~-state whereas g increases slightly for 15SGd. The half-life of the 4+ state of t58Gd was remeasured as 158Gd: T1/2(4+)= 148(2)ps. A measurement of the rotation in the 4~ state of lS6Gd in external magnetic fields of various strengths up to B~xt=9.5 T did not confirm the anomalous dependence of the magnetic hyperfine field in gadolinium metal on the external field, which has been reported by Persson et al. [29].

The static hyperfine field of B472K(ErHo)=739 (18) The results are discussed and compared with theoretical predictions.

The ~-factor of the 589 keV state of l~TIn has been determined by a measurement of the rotation of the 1,303-273 keV 7-7 directional correlation in an external magnetic field of 9.55(1)T. The result, g3/2(589 keV)= +0.068 (39), contradicts the usual interpretation of the state as the 2p3/2 single proton hole configuration for which the Schmidt value is ga/2-(Schmidt)= +2.53. It favours the interpretation as the first rotational state built up on the single proton [301] 1/2-Nilsson orbit in a strongly deformed core of prolate shape.

The g-factor of the 2 + rotational state of 184W was redetermined by an IPAC measurement in an external magnetic field of 9.45 (5)T as: g2+ (184W) = + 0.289 (7).In the evaluation the remeasured half-life of the 2 + state: T1/2 (2 +) = 1.251 (12) ns was used. TDPAC-measurements with a sample of carrierfree 184Re in high purity iron gave the hyperfine fields: A comparison with the hyperfine field known from a spin echo experiment with lS3WgFe leads to the hyperfine anomaly:184W2+ A 183Wg= +0.145(36).The hyperfine splitting observed in a M6ssbauer source experiment with another sample of carrierfree 184"Re in high purity iron indicates that the smaller splitting, measured previously by a M6ssbauer absorber experiment is due to the high tungsten concentration in the absorber. The new value for the g-factor of the 2 + state together with the result of the M6ssbauer experiment allow an improved calibration for our recent investigation of the gR-factors of the 4 + and 6 + rotational states. A detailed investigation of the attenuation of Y-? angular correlations in liquid sources of lS~Re and aS4mRe revealed the reason for erroneous results of early measurements of the 2--gR-factor: The time dependence of the perturbation is not of a simple exponential type. It contains an unresolved strong fast component.

The g-factor of the 159 keV 3/2 + state of 117Sn has been determined by the integral perturbed angular correlation (IPAC) method in an external magnetic field of 9.47 T. The result: g3/2+ = +0.439 (31) favours the interpretation as a rather pure d 3/2 single neutron quasiparticle state.
