γ-UMo_2O_8 as a New Polymorph of Uranium Dimolybdate Containing Tetravalent Uranium

摘要

In the last few years, uranium-containing minerals and inorganic compounds have attracted increasing interest in connection both with their important role in the processes of the transmutation of spent nuclear fuel [1] and with their possible use as host materials for the immobilization of transuranium elements (first of all, weapons-grade plutonium) and radionuclides [2,3].
