This paper provides an introduction to perturbed angular correlation (PAC) spectroscopy in
the context of its application in the study of point defects and diffusion. It emphasizes what …

Several experimental techniques are available to investigate materials but microscopic
techniques based on hyperfine interaction form a subclass that can characterize materials at …

Hydrogen-vacancy interaction in tungsten was investigated by means of the perturbed
angular correlation technique, using the isotope 111 In as a probe. Hydrogen trap** at an …

Following do** with In 111 in O 2 gas at 1273 K, samples of La 2 CuO 4+ y were
subjected to vacuum anneals of varying lengths to adjust the oxygen content. Susceptibility …

The perturbed angular correlation (PAC) method has been employed to study the hyperfine
interaction of the 245-keV state in Cd 111, following In 111 implantation into the fcc metals …

Atomic defects which migrate and trap at impurity probe atoms can be labelled by the
changes they induce in the hyperfine interactions of the probe nuclei. Many studies have …

The electric field gradients (EFGs) of 111 Cd at substitutional sites in binary oxides of
different crystal structures obtained in perturbed angular correlation (PAC) experiments are …

The time-differential perturbed-angular-correlation (PAC) method with ion-implanted In 111
tracers was employed to study the hyperfine interactions of Cd 111 nuclei in the rare-earth …

Silver clusters with size ranging from a few nanometers to several nanometers are formed in
zirconia matrix and have been characterized by low frequency Raman scattering (LFRS) …

Perturbed angular correlation studies on hafnium foil subjected to annealing in oxygen
atmosphere show that there exists three distinct Hf sites which are identified as probe atoms …
