Atomic jump frequencies in intermetallic compounds studied using perturbing angular correlation of gamma rays
(2012-08)Atomic jump frequencies were determined in a variety of intermetallic compounds through analysis of nuclear relaxation of spectra measured using the nuclear hyperfine technique, perturbed angular correlation (PAC) of gamma ... -
Site preferences and jump frequencies of In/Cd solutes in rare earth palladium phases having the L1 sub 2 structure
(2012-07)The method of Perturbed Angular Correlation of gamma rays (PAC) was used to study site preferences of indium solutes and jump frequencies of cadmium impurities in rare-earth palladium phases RPd sub 3 which has the L1 sub ... -
Lattice locations and diffusion in intermetallic compounds explored through PAC measurements and DFT calculations
(2012-05)Site preferences of 111In/Cd impurity probe atoms were studied as a function of composition in Al3Ni and as a function of temperature in Al3Ti and Al3Zr structures using perturbed angular correlation of gamma rays (PAC). ... -
Indium solubility in α-gallium and gallium-indium eutectic alloys studied using PAC
(2011-08)The melting temperature in α-gallium is 303K. The method of perturbed angular correlation of gamma rays (PAC) was used to determine the solubility of 111In probe atoms present at of 10-10 mole fraction. Below 303K and above ... -
Nuclear relaxation in CoGa3 lattice structures
(2010-01)Perturbed Angular Correlation (PAC) Spectroscopy is a method utilized to study hyperfine interactions within solids by observing the gamma rays emitted by the nuclear decay of probe atoms that have been artificially infused ...
