We have measured the plasmon resonance response of the cleaned and well characterized surfaces of various plutonium thermal allotropes using electron energy loss spectroscopy (EELS).1,2 The energy of the plasmon resonance in the plutonium is highly dependent upon the electronic structure of the solid, and in particular, the electron density or number of electrons available for conduction. Using this method we probe directly for the first time the number of free electrons, and the possible changes in the degree of f-electron localization between the various Pu allotropes. © 2000 American Institute of Physics.

    Pure plutonium is an exotic metal that is poorly understood. The α-Pu phase (zero-temperature ground state) is believed to have mainly itinerant 5f electrons. However, δ phase (fcc) is believed to be in neither limit (neither completely itinerant nor localized), that we may describe as...
