摘要：

In situ, interference-enhanced Raman scattering of ultrathin, solid solution films of Rb(x)C60 (0 less-than-or-equal-to x less-than-or-equal-to 3) prepared in UHV are reported. Variations of phonon linewidths of both selected low-frequency, radial and high-frequency, tangential intramolecular modes indicate strong electron-phonon coupling. The results directly support a recent theory for phonon-mediated superconductivity in alkali-C60 systems.
