Phonons and UO$_2$ Debye-Waller factors in sublattice model
Temperature dependence of UO$_2$ Debye-Waller factors is calculated for Born-Mayer model in <<frozen>> sublattice approximation. The results are known to be in good agreement with the experimental data in temperature range from 0 to 1500 K, i. e., up to a superionic transition.
