Crystals of n-type Ge were bombarded with 3. 5 mev electrons at 20-30 C and annealed in 10** minus **4-10** minus **5 torr vacuum by heating at a rate of 3-4 deg/min to 400-600 C to determine the damping decrement Q** minus **1 of flexural vibrations of a sample during annealing and to determine the temperature dependence of the resonance frequency. The measurements were carried out at 1-8 kHz corresponding to the second and fourth resonance vibration modes of amplitudes of the order of 10** minus **5.
