 note = {Ultraviolet photoelectron spectra (UPS) of metallofullerene, La2@C78 were measured using a synchrotronradiation light source. Its spectral onset energy was 0.70 eV below the Fermi level, indicating the semiconductive nature of this metallofullerene. The UPS consisted of numerous crests and troughs. Further, a change in intensity upon tuning the excitation energy was observed; however, the intensity of the change was not as large as those observed for other fullerenes. The UPS of La2@C78 differ considerably from those of Ti2C2@C78, although they are thought to have the same cage structure. Herein, this difference is explored using density-functional theory, and the origin of this difference was determined to be the hybridization of the π-electron wave functions.},
