摘要：
Measurements of the superconducting T(c) and Raman spectra in isotopically modified Rb3C60 are reported. A decrease in T(c) of 0.65 +/- 0.10 K in samples with (75 +/- 5)% substitution of C-13 for C-12 yields an exponent of alpha = 0.37 +/- 0.05. This is interpreted as evidence for phonon-mediated pairing.
