    • EELS spectra were obtained with an energy resolution of ∼1 eV using a Philips CM300 field-emission-gun transmission electron microscope (TEM) equipped with a Gatan imaging filter. The accelerating voltage of the TEM of 300 keV largely exceeds the energy of the actinide 4d → 5f excitation, so that these are governed by electric-dipole transitions; see, e.g., R. F. Egerton, Electron Energy-Loss Spectroscopy in the Electron Microscope (Plenum Press, New York, 1996). EELS was recorded in imaging mode using a collection angle of 6 mrad, allowing the 000 beam and first-order reflections to contribute to the spectra The sample thickness was ∼0.5 inelastic mean free path, as calculated by the zero-loss and plasmon peaks. Samples were 99.9% pure and prepared via either electropolishing or ion milling. While Th and U could be handled directly, all Pu work was performed in a glove box, and samples were transported in a vacuum-transfer holder due to the toxic nature of the metal [for sample preparation procedures, see K. T. Moore, M. A. Wall, and A. J. Schwartz, J. Nucl. Mater. 306, 213 (2002)].
