ABSTRACTInternal oxidation of indium in a silver matrix is studied by time-differential perturbed angular correlations. The oxidizer treatments were performed in air at 1 atm. Our results are consistent with the formation of different In-O complexes.

Abstract This paper gives an elementary introduction to time differential perturbed angular correlation of γ-rays emitted from excited nuclei with particular reference to nuclear quadrupole interactions. We start with a comparison to other techniques such as nuclear quadrupole resonance and the Mössbauer effect, quote all necessary formulae, describe a typical spectrometer, list suitable isotopes, and finally give some examples for modern applications.

Motional Correlation Time

ABSTRACTThe motional correlation time, τc, in liquid Se and Se-rich Se-Te alloys has been investigated between 500 and 900°C using time differential perturbed angular correlations of y-rays from dilute 111Cd impurities. In all alloys we find τc ∝ exp (E0/kT) at low T where E0 = 0.36 eV. τC deviates from this relation at high T. At low T, τCis tentatively identified as the lifetime of a Cd to host molecule bond, and at high T as the average lifetime of bonds in the host molecule.

Asymmetry Parameters

The nuclear quadrupole interaction of 187W(β-)187Re in W(VI)-EDTA complexes at room temperature was determined by time differential perturbed angular correlations (TDPAC) to be VQ = 1270(8) MHz with an asymmetry parameter η= 0.403(4). While the coordination geometry of the Mo(VI)- EDTA complex is known, there appears to be none for the W-analogue. The rather similar asymmetry parameters for the 187W(β-)187Re in W(VI)-EDTA complex and for the 99Mo(β-)99Tc in Mo(VI)- EDTA complex, determined previously, supports the idea that the coordination geometries in the Moand W-complexes are similar
