“…( 1 ). Powder XRD was earlier used to ascertain the phases measured by µ-RS when bibliographic information was limited [ 9 , 13 , 18 , 19 ]. ND provides complementary information to p-XRD because neutrons interact with the point-like nucleus of an atom, whereas X-rays interact with the extended electron cloud surrounding the atom.…”

This work presents the results for identification of chemical phases obtained by several laboratories as a part of an international nuclear forensic round-robin exercise. In this work powder X-ray diffraction (p-XRD) is regarded as the reference technique. Neutron diffraction produced a superior high-angle diffraction pattern relative to p-XRD. Requiring only small amounts of sample, µ-Raman spectroscopy was used for the first time in this context as a potentially complementary technique to p-XRD. The chemical phases were identified as pure UO2 in two materials, and as a mixture of UO2, U3O8 and an intermediate species U3O7 in the third material.Electronic supplementary materialThe online version of this article (10.1007/s10967-017-5666-3) contains supplementary material, which is available to authorized users.
