Abstract
The discovery of a large internal-friction peak in amorphous selenium around 30K at 160 MHz is reported. The peak appears on the attenuation of ultrasonic shear waves and is well explained with a distribution of activation energies from 0 to 130K. Moreover, this distribution involves an attenuation law at low temperature which is indeed observed experimentally.Keywords
