Temperature dependence of Raman scattering in a pressure-induced superconductor Cs3C60 was studied under ambient pressure between 2 and 290 K. The contributions of the intramolecular vibration modes to electron-phonon coupling were evaluated by comparing the linewidths of the modes in Cs3C60 with those in pristine C-60. The total electron-phonon coupling constant lambda was approximate to 0.18, approximately one-third of the values for Rb3C60 and K3C60. Temperature-dependent Raman scattering in the superconductor Rb3C60 and a non-superconductor Rb6C60 was also measured for comparison. (C) 1998 Elsevier Science B.V. All rights reserved.
