After perfecting a technique to manufacture extremely pure, homogeneous, smallconcentration Sn in Pb samples, we have measured the Debye-Waller factor over the temperature range of 4 to 300 K. Our data show some evidence of a line broadening between

We have measured the dose dependence of the degree of amorphization of titanite, CaTiSiO(5). Titanite is an often metamict mineral which has been considered as a matrix for the encapsulation of radiogenic waste, such as Pu. The amorphous fraction p o

Ambient pressure Moessbauer spectra of Mg(0.9)Fe-57(0.1)SiO3 perovskite synthesized at pressure-temperature conditions of about 50 GPa and 1700 K show that the iron is entirely high-spin Fe(2+) and appears to be primarily located in the octahedral si
