Photoelectron spectra of the metallofullerene Tb@C-82 (I) were measured using a synchrotron radiation source. The band intensity of the Tb@C-82 (I) spectra was found to depend on the incident photon energy, as has been observed for other fullerenes. The spectral onset energy is 0.25 eV below the Fermi level. This value is nearly equal to that for La@C-82 (I) and is smaller than that for the empty C-82. The spectral shapes of Tb@C-82 (I) resemble those of La@C82 (I). (C) 2004 Elsevier B.V.
