Abstract
The authors report C-13, Rb-87, and Cs-133 nuclear magnetic resonance measurements of line shapes and Knight shifts in the normal and superc onducting states of Rb3C60 and Rb2CsC60, and deduce the temperature de pendence of the electron spin susceptibility. The results are in good agreement with the BCS theory in the weak-coupling limit: 2DELTA0 = 3. 52kT(c).
