Abstract: Valence-band photoelectron spectra of Pu2C3 and PuC0.85 reveal the same type of 5f features below the Fermi level as observed for the majority of other Pu systems. They appear at the same energies (0¿0.1, 0.5, and 0.85 eV) and their intensity is higher for Pu2C3 than for PuC0.85. We deduce that they can be attributed to the 5f5 final-state multiplet originating in the 5f6 component of the ground state. The higher 5f occupancy (5.48), calculated in Pu2C3, explains its non-magnetic character.
