Abstract

Raman spectra have been measured on BaxC60 binary systems for x=3,4 and 6. The pentagonal pinch Ag(2) mode exhibits a softening in an approximately proportional manner to the formal valence of C60 molecule. This result suggests that the valence of Cgo in Ba doped systems are understood by the naive ionic crystal model based on Ba2+. The broader Raman peaks in superconducting BaC60 indicates that the electron-phonon interaction is considerably large comparing to those for 833050 and BagC-.
