Debye-Waller factors of compounds with the caesium chloride structure

The lattice dynamics of five compounds with the caesium chloride structure have been investigated using shell models. Debye-Waller factors for these c ompounds are calculated over the temperature range from 1 to 1000 K and the results are presented analytically in a polynomial form. When experimental results are available, the calculated results are compared to the experime ntally measured Debye-Waller factors and typically the discrepancies betwee n these factors are less than 10%.
