State of iron atoms in synthetic ferrite garnets and zirconolites—matrices for disposal of actinide-containing waste

Synthetic ferrite garnets and zirconolites containing La, Ce, Gd, and Th as simulators of radioactive actinides have been investigated by ⁵⁷Fe Mössbauer spectroscopy. The state of iron atoms in the samples studied and their distribution over crystallographically nonequivalent structural positions are established. The crystallochemical formulas are refined and space groups are determined for a number of ferrite garnets and zirconolites.     

A canonical setting and separating times for continuous local martingales

The notion of a separating time for a pair of measures on a filtered space is helpful for studying problems of (local) absolute continuity and singularity of measures. In this paper, we describe a certain canonical setting for continuous local martingales (abbreviated below as CLMs) and find an explicit form of separating times for CLMs in this setting.
