Thermal Expansion and Ionic Conductivity

The cumulant expansion of the EXAFS Debye-Waller factor is discussed for the polarized and nonpolarized K EXAFS formulae. The improved formula for the nonpolarized Irs turns out to give a shorter near-neighbour distance than the value obtained by the expansion derived previously. Specifically, in CuBr at around 600 K its difference is about 0.01 AA.
