| Abstract: | Raman scattering is observed from the vibrations of the mobile sodium and silver ions in β-alumina between 4.2 and 900°K. The frequency response is Lorentzian at all temperatures above 300°K with little change in frequencies and damping rates. It is concluded that diffusive conduction with a well-defined attempt frequency predominates up to 900°K. |
