Abstract
We report ballistic phonon experiments in semi-insulating GaAs as a function of polarization and propagation direction and of the concentration of chromium in the crystal. The data provide direct evidence for a tetragonally distorted site symmetry of the Cr ions and a ground-state splitting at ~14 K.
