Abstract

Electron-phonon interactions in solid C60 have been studied by transient Raman spectroscopy on a picosecond time scale. The electrons were photoinjected into the triply-degenerate states of solid C60 by an ultrashort laser pulse of photon energy ω=2.14 eV. These energetic electrons relax by emitting various phonons. By monitoring the phonon occupations at very low temperatures with anti-Stokes Raman scattering, direct information about the relative strength of the electron-phonon interactions in solid C60 was obtained. Our experimental results demonstrate that electrons interact much more strongly with the low-frequency radial A g mode than the other phonon modes in solid C60.
