摘要：

Rb-87 (and Rb-85) NMR spectra in the orthorhombic phase ( (o) phase) of Rb1C60 show up broadening, with respect to the high-T cubit phase and to the quenched phase, which signals change of symmetry of the Rb site. The spin lattice relaxation rate follows a linear T dependence in the (o) phase above 100 K, suggesting that this phase is metallic. The increase of 1/T1T at low T seems to be correlated with the transition seen by E.S.R.
