ABSTRACT Plutonium metal is a very unusual element, exhibiting six allotropes at ambient pressure, between room temperature and its melting point, a complicated phase diagram, and a complex electronic structure. Many phases of plutonium metal are unstable with changes in temperature, pressure, chemical additions, or time. This strongly affects structure and properties, and becomes of high importance, particularly when considering effects on structural integrity over long periods of time [1]. This paper presents a time-dependent neutron total scattering study of the local and average structure of naturally aging δ-phase 239Pu-Ga alloys, together with preliminary results on neutron tomography characterization.

AbstractThe structure of amorphous silica has frequently been compared with its crystalline counterparts in an attempt to understand the glass structure beyond short-range correlations. This paper presents results from neutron total scattering measurements of several polymorphs of silica and shows how these can be used to make a direct, quantitative comparison of amorphous and crystalline forms. It is found that the glass is similar to HP-tridymite and β-cristobalite, both dynamically-disordered crystalline phases of silica, but only out to distances ∼7.5 Å, beyond which the structures diverge. This is too small to validate a microcrystallite theory of glass structure. It is the average 180° Si–O–Si linkage in these two crystalline phases which gives them the flexibility for their instantaneous disordered structure to resemble the quenched (static) glass structure.
