title = "INVESTIGATION OF METAMICT AND ANNEALED NATURAL PYROCHLORES BY X-RAY ABSORPTION SPECTROSCOPY.",
abstract = "The pyrochlore structure type is a common phase in polycrystalline waste forms. A principal concern has been the effect of alpha-recoil events on the long-term stability of these phases. Naturally occurring minerals of the pyrochlore group provide an example of the full range of radiation effects from fully crystalline to x-ray diffraction amorphous (the metamict state). X-ray absorption spectroscopy is used to investigate the coordination geometry of Ti-sites in metamict and annealed pyrochlores. The principal effects in the fully-damaged material compared to annealed samples include an increase in the asymmetry of the Ti-site and a slight reduction in bond length and coordination number.",
