摘要：

The temperature dependence of the elastic constants C11, C12 and C44 has been studied in the orientationally disordered cubic phase of rubidium cyanide by Brillouin spectroscopy. A strong softening of the elastic constant C44 is observed. The elastic constant C11 shows a linear decrease approaching the phase transition, while the elastic constant C12 increases linearly with decreasing temperatures in the room temperature phase, rather similarly to the behaviour of KCN and NaCN. © 1979.
