Atom motion in solids following nuclear transmutation
Gary S. Collins
Following nuclear decay, a daughter atom in a solid will "stay in place" if the recoil energy is less than the threshold for displacement. At high temperature, it may subsequently…
Diffusion and equilibration of site-preferences following transmutation of tracer atoms
Gary S. Collins
Using the method of perturbed angular correlation of gamma rays, diffusional jump-frequencies of probe atoms can be measured through relaxation of the nuclear quadrupole interactio…
Site occupation of indium and jump frequencies of cadmium in FeGa3
Randal Newhouse, Gary S. Collins, Matthew O. Zacate
Perturbed angular correlation (PAC) measurements using the In-111 probe were carried out on FeGa3 as part of a broader investigation of indium site occupation and cadmium diffusion…
Trapping of solute atoms at grain boundaries in GdNi2
Ryan Murray, Debashis Banerjee, Gary S. Collins
Lattice locations of 111In impurity probe atoms in intermetallic GdNi2 were studied as a function of alloy composition and temperature using perturbed angular correlation spectrosc…
Solute-solute interactions in intermetallic compounds
Debashis Banerjee, Ryan Murray, Gary S. Collins
Two types of solute-solute interactions are investigated in this work. Quadrupole interactions caused by nearby Ag-solute atoms were measured at nuclei of 111In/Cd solute probe ato…
Thermodynamic model of solute site preferences in ordered alloys
Gary S. Collins, Matthew O. Zacate
A thermodynamic model based on the law of mass action is used to calculate concentrations of elementary point defects and to determine site preferences of solute atoms in ordered a…
Impurity diffusion in highly-ordered intermetallic compounds studied by nuclear quadrupole interactions
Gary S. Collins, Qiaoming Wang, John P. Bevington
Diffusion of impurity atoms depends on the sublattices occupied, active diffusion mechanisms, and jump frequencies to neighboring sites. The method of perturbed angular correlation…
Nuclear quadrupole interactions of 111In/Cd solute atoms in a series of rare-earth palladium alloys
Qiaoming Wang, Gary S. Collins
Nuclear quadrupole interactions were measured at 111In/Cd probe atoms in rare-earth palladium phases RPd3 having the L12 structure using the technique of perturbed angular correlat…
Determination of the crystal structures of In70-Ni30 and In70-Pd30 using perturbed angular correlation
Lee Aspitarte, Egbert R. Nieuwenhuis, Gary S. Collins
According to phase diagrams based on x-ray measurements, In70-Pt30 has the cubic Sn7Ir3 crystal structure (D8f, cI40) but the alloys In70-Ni30 and In70-Pd30 have been variously rep…
Comparison of jump frequencies of 111In/Cd tracer atoms in Sn3R and In3R phases having the L12 structure (R = rare-earth)
Megan Lockwood Harberts, Benjamin Norman, Randal Newhouse +1
Measurements were made of jump frequencies of 111In/Cd tracer atoms on the Sn-sublattice in rare-earth tri-stannides having the L12 crystal structure via perturbed angular correlat…
The solubility of indium in liquid gallium supercooled to 12 K
Xiangyu Yin, Gary S. Collins
The method of perturbed angular correlation (PAC) was used to determine lattice locations of 111In impurity probe atoms present in extreme dilution in the intermetallic compound Fe…
Diffusion in LanCoIn3n+2 phases studied by perturbed angular correlation
Randal Newhouse, Gary S. Collins
Jump frequencies of 111In/Cd tracer atoms were measured for a series of layered phases LanCoIn3n+2 using the technique of perturbed angular correlation of gamma rays (PAC). The fre…
Diffusion in binary and pseudo-binary L12 indides, stannides, gallides and aluminides of rare-earth elements as studied using perturbed angular correlation of 111In/Cd
Randal Newhouse, Justine Minish, Gary S. Collins
Diffusional jumps can produce fluctuating electric field gradients at nuclei of jumping atoms. Using perturbed angular correlation of gamma rays (PAC), jumps of probe atoms cause n…
