摘要：
A single peak at 123 meV has been found in the neutron inelastic-scattering spectrum of PuO2 measured on the PHAROS chopper spectrometer at LANSCE. This is ascribed to the Gamma(1) to Gamma(4) transition of the ground-state crystal-field multiplet and quantitative agreement is obtained between the observed and calculated cross section. The peak is broadened beyond the instrumental resolution. A short discussion is presented on how this observation complements our understanding of the actinide oxides. [S0163-1829(99)02602-8].
