摘要：
Using general expressions for the velocity and ultrasonic attenuation coefficient we have analyzed ultrasonic data for the 208-K phase transition in RbAg4I5. From fitting the velocity in the high-temperature phase we obtain values for the strain and pseudospin coupling constants. We extract the intrinsic pseudospin relaxation rate from an analysis of the attenuation. The Jahn-Teller model is found to provide a good description of the ultrasonic behavior associated with the phase transition. © 1979 The American Physical Society.
