Abstract
The internal friction Q(-1) and shear modulus G measurements of CsH2AsO4 cr ystal have been carried out in the temperature range from 20 to 175 degrees C. Two peaks were found in the Q(-1)(T) curves, the first peak is near roo m temperature, the second is at 162 degrees C and it is related to the phas e transition from paraelectric to superionic phase. It is proposed that the disordering in proton and I-I-bond network is responsible for Q(-1) and G anomalies observed.
