We have used an original modulation technique to measure longitudinal (spin-lattice) relaxation time T1 in stable and metastable phases of RbC60 at 77 - 450K. The data are correlated with transverse relaxation time T2 and spin susceptibility measured in the wide temperature range . The equality T1 = T2 is found to be valid both in the stable polymer (ortho-I) and fee phases. In quenched samples, two different T1 values are found below 140K, one of them being much longer than T2. Interpretation is suggested implying quasi 1D metal behavior in the polymer phase and localized paramagnetic centers with exchange interaction in the others.
