N2 - Electron paramagnetic resonance (EPR) of the triplet centers and dynamic 29Si nuclear polarization was studied in irradiated naturally abounded (4.7%) and 29Si isotope enriched (99.3%) silicon crystals. Saturation of the EPR lines of the photoexcited triplet centers with nonequilibrium spin polarization between ms = +1, 0, and -1 sates leads to the nuclear polarization ≈7000 times higher than equilibrium value. It was shown that the observed dynamic nuclear polarization is a result of the "solid-effect".
