title = "Local structure analysis around Kr in minerals by XAFS",
abstract = "In order to investigate reactivity of noble gas (Kr) in minerals, several kinds of Kr-doped minerals were synthesized under high pressures and temperatures and were subjected to mass spectroscopy and XAFS. We observed that some Kr trapped in the samples was retained in the samples at temperatures above 1000 °C. Interestingly, the atomic distances between Kr and neighboring atoms derived from XAFS analysis appeared to be shorter than the distances expected for the case of simple adsorption. These results suggest that Kr might be bound in the samples with interaction stronger than the adsorption and/or exist in the internal sites of the structure of the host minerals (not in a grain boundary as is often presumed).",
