Measurements are reported of the microwave Faraday effect at a frequency of 33 GHz in samples of n‐type Ge with carrier concentrations ranging from 5 × 10 15 to 3 × 10 17 cm −3 . From these results the anisotropy of the momentum relaxation time for pure ionized impurity scattering is found to have a value of K τ ( i ) = 11 ± 1. This value is comparedwith results from previous experimental investigations and is in good agreement with theoretical predictions.
