| Abstract: | A series of spin resonance experiments on samples illuminated with light at photon energies ?ω>Eg are reported. The results set an upper limit on the quantum efficiency for photoproduction of unpaired spins, γs? 2×10-7,implying that the photo-induced excited states and the photo-generated carriers are spinless and are to be associated with charged solitons. |
