    Notes: Abstract Perturbed γ-ray angular distributions from the first 2+ states were measured for Coulomb-excited192,194,196,198Pt recoiling into vacuum atv/c=0.010. Comparableg-factors were obtained for all four nuclei. Normalisation to the hyperfine field in196Pt enabled both a comparison with a recent hydrodynamicg-factor measured in192Pt and a cross-check of disputed Ir in Fe measurements. The followingg-factor was obtained:g(316 keV, 2+;192Pt)=0.32(3).

    The electric fieldgradient at Cd-impurities in heavy rare earth metals (1973)

    Notes: Abstract The static electric quadrupole interaction of111Cd in the heavy rare metals Gd, Tb, Ho and Er has been studied at room temperature by time differential perturbed angular correlation techniques. From these measurements the effective electric field-gradient,V zz eff , at the Cd-site was derived on a relative scale. The lattice contributions,V zz lat , to the total electric fieldgradient have been determined by lattice-sum calculations. The ratioα=V zz eff /V zz lat , which to a certain extent represents the conduction electron contribution to the electric fieldgradient, decreases with increasing atomic number. Possible reasons for this behaviour are discussed.

    Study of the electric quadrupole interaction at Ta impurities in rare earth metal hosts (1974)

    Notes: Abstract The time differential perturbed angular correlation technique has been used to measure the electric fieldgradient (EFG) at the site of181Ta impurities in the heavy Rare Earth metals Gd, Tb, Dy, Ho and Er at room temperature. It is found that the ratio α ≡ ¦V zz eff /V zz lat ¦ between the measured EFGV zz eff and the lattice EFGV zz lat , which is known from lattice sum calculations, is in the order of α≃300, suggesting that an important contribution to the EFG is due to electrons localized at the impurity. The ratio α is not constant throughout the Rare Earth series. It decreases from Gd to Tb and increases between Tb and Er. This behaviour is compared to the results of a previous investigation with the impurity Cd in the same hosts.
