摘要：
The low-temperature mobility saturation found in a nondegenerate 3D electron gas at strong charged-impurity scattering was shown to be due to quantum mobility edge existence. The negative magnetoresistance caused by magnetic field suppression of interference corrections to the conductivity was observed. The corrections were found to be small near the mobility edge.
