N2 - We have performed low-temperature ultrasonic attenuation measurements on bulk single-crystalline silicon irradiated with a fast-neutron dose of 3.2 × 1021 n/cm2 (E > 0.1 MeV) at a frequency of 283 MHz. The data are analyzed in the framework of the tunneling model (TM). A comparison of these results with those obtained from similar measurements performed on neutron-irradiated quartz is made in view of the differences in radiation damage. We found that the irradiation dose has to be three orders of magnitude higher for silicon than for quartz in order to obtain the same effect in the ultrasonic attenuation.
