Abstract
The spin-lattice relaxation kinetics of radical cation C60+ in polycrystalline C60 has been studied at room temperature by two-pulse delayed nutation and nutational echo methods. It has been found that the kinetics is well described by a function exp(-a(root)t), as expected when the distribution of relaxation time of paramagnetic centers takes place. Our results suggest that oxygen molecules cause the observed kinetics. These molecules play role of fast-relaxing impurities and accelerate spin-lattice molecules cause the observed kinetics. These molecules play role of fast-relaxing impurities and accelerate spin-lattice relaxation of C60+ radicals. The earlier obtained peculiarities of C60+ radical relaxation in fullerites are discussed.
