REDETERMINATION OF THE C-13 KNIGHT-SHIFT IN K3C60

Due to the absence of suitable reference substance, previous determina tions of the C-13 Knight shift in K3C60 are incorrect. We propose that K3C60(THF)(3) should be a good reference for the Knight shift measure ment and with this new reference we find that the C-13 Knight shift in K3C60 is only 6ppm, indicating that the electronic density of states for K3C60 at the Fermi level in normal state is relatively lower, whic h agrees well with previous photoemission results.
