title = "INVESTIGATION OF URANIUM L-EDGES OF METAMICT AND ANNEALED BETAFITE.",
abstract = "The uranium site in naturally occurring metamict minerals of the pyrochlore group has been investigated using x-ray absorption spectroscopy (XAS). Pyrochlore structures are common phases in proposed polycrystalline waste forms. Betafite, a member of the pyrochlore group, exhibits U-O bond lengths of 1. 94 and 2. 37 A for the metamict state, and 2. 03 and 2. 51 A for the crystalline (annealed) state. The U-O bond lengths decrease and there is a disruption in the second nearest neighbor periodicidy as material is converted from the crystalline to the metamict state.",
