摘要：

Dynamic nuclear polarization of the Si-29 nuclei due to the "solid-effect" was observed clearly after saturation of the phosphorus electron paramagnetic resonance lines in three kinds of silicon crystals containing different amount of the Si-29 isotope (1%, 4.7%, and 99.3%). Maximal enhancement (E) of the room-temperature Si-29 nuclear magnetic resonance signals E approximate to 605 was obtained at the temperatures of 10-14 K in silicon containing 1% of the Si-29 isotope.
