S. Collins
Present Position
Professor of Physics and Astronomy
Education
Bachelor of Arts, Physics, Rutgers College
Doctor of Philosophy, Physics, Rutgers University
Research Interests
Application of hyperfine interaction methods using radioactive probes, in particular perturbed angular correlation of gamma rays (PAC) to study the local structure and properties of solids:
- Point defects
and defect interactions
- Lattice location
of dilute solutes in compounds
- Diffusion measured
by jump frequencies of probe atoms
This group is currently the only one in the US using PAC to study solids. More information and downloads of publications can be found at http://defects.physics.wsu.edu
