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…
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…
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…
