Özet
87Rb NMR relaxation measurements in superconducting fullerene Rb3C60 for various values of the external field are reported. In the normal state the results are in agreement with T1T= Constant. Below Tc, while no evidence of Hebel-Slichter peak is present in temperature dependence of T1-1 , maxima are observed in \( T2-1 at T=22K characteristic of vortex field fluctuation. T1 shows an anomalous field dependence not yet explained.
