Electronic Phases and Ageing of Plutonium

The action of pressure can change, besides the crystalline structure, the material electronic structure. This phenomenon can create conditions for radioactive material structural and compositional instability during storage. The paper presents results of processing of P. Bridgman’s experimental data on static compression of uranium and plutonium metal samples which testify for the existence of two various uranium electronic phases and three plutonium phases up to a pressure P=10 GPa. The electronic phases of solids were originally discovered when pronounced changes in material properties (for example, compressibility), without any change in the material crystalline structure, were detected in experiments under pressure.
