Abstract: | We estimate the numerical contribution of the interaction between like defects in glasses for the linewidth (? T?12) obtained in acoustical experiments. This interaction gives origin to a diffusion process with a very large diffusion constant (D = 10?5 cm2 sec?1). The thermal conductivity due to this diffusion process is calculated. Its temperature dependence is also obtained. |
