Abstract
The phonon scattering by shallow acceptors in Si has been observed to decrease rapidly with magnetic field at high fields and low temperatures. This is the behavior expected for the ground-state quartet of the undistorted site. The scattering by shallow acceptors in Ge is, however, almost independent of field, indicating a quite different ground-state structure. This is believed to be the result of a dynamic Jahn-Teller distortion.Keywords
