摘要：

Results of time-resolved cw-EPR and spin-echo measurements of photoexcited C-60 are presented, It is found that visible light induces a reversal in sign of the spin polarization of paramagnetic impurities present in solid C-60. The photoinduced spin polarization is explained in terms of spin-selective triplet exciton quenching by the spin 1/2 paramagnetic centers.
