| Abstract: | It is shown that the illumination of samples leads to the appearance of anomalies in the temperature dependences of the propagation
velocity of longitudinal ultrasonic waves along the principal crystallographic directions of proustite (Ag3AsS3) at T∼150 K. The features discovered are associated with a photoinduced phase transition caused by restructuring of the cation
sublattice of proustite.
