Black.1 There is a large discrepancy between this calculation and experimental data. It is proposed that this is due to large displacements of the interstitial charge compensating F- ions in the host lattice. Preliminary results indicate that they have sufficient mobility and can move quickly enough to cause a faster relaxation time than has been calculated.29 ppengCopyright is held by the author, unless otherwise indicated.
