Abstract Rb3C60 single-crystal thin films were prepared on the cleaved (111) surface of C60 single crystal. The photoemission spectrum line shapes of the lowest unoccupited molecular orbital (LUMO) derived band at room temperature and 150 K were established by the synchrotron radiation photoemission spectrum measurements. The density of states near the Fermi level was distinctly affected by temperature. No less than six sub-peaks of the LUMO band were observed even at room temperature. The existence of so many sub-peaks offered the opportunities to analyses in more detail the orientational structure and the electron-Boson interactions of the narrow-band metallic Rb3C60.
