Abstract
New measurements of saturable ultrasonic attenuation in the frequency range 170-600 MHz, below 1 K, are reported in amorphous together with previous results at lower frequencies. Contrary to predictions of the two-level system tunneling theory, linear frequency dependence and essentially no temperature dependence of the saturable ultrasonic attenuation were observed.
