In this project, the displacement of defect ions and atoms in                   insulating crystals will be studied.  Paraelectric resonance                    experiments, using hydrostatic pressure, will investigate the on- to            off-center transitions in several systems.  EXAFS (extended x-ray               absorption Fine Structure) will measure directly, independent of the            charge state, the off-center displacement of ions or atoms such as              Ag;s+, Cu;s+, Co;s2;s+, Ag;so and Cu;so.  In some cases, it will                measure for the first time, the distortion of the lattice about an              off-center defect.  Data will also be obtained for the cation - anion           distances in several series of defect systems in which the position of          the defect varies from off-center to on-center.  Some of these data             will test Vegard's Law in systems for which there is a large difference         in ionic radii.  These experiments will provide needed information              about the conditions required for off-center behavior.
