Popis:	The influence of light illumination on the nonelastic properties of high-resistivity light-sensitive CdS crystals under ultrasound (the so-called photoacoustic effect (PAE)) is studied. It is shown that the crystal steady state is attained with two different characteristic times τ1 and τ2 (τ1 ≪ τ2), which correspond to switching on (>1) and switching off (τ2) light, respectively. The PAE sign (i.e., the increase or decrease in the ultrasonic attenuation) under illumination is not a permanent characteristic of CdS crystals.
