Abstract
The distribution of the probability density function (pdf) for the sam ple quenched from 970 K (970Q) shows more anharmonicity than that for the slowly cooled sample (SC) and is spreading out along the [111] dir ections towards the center of the elementary cell, and the one particl e potential of fluorine ion in 970Q is less steep than that in SC towa rds the unoccupied center. The fact is correlated to the results of th e conductivity measurements reported in 1985 by Ito et al.
