Annotation

The variation of Debye-Waller factors and mean square displacements at different temperatures for simple bcc metals Li, Na, Rb and Cs is studied using pseudopotential proposed by Fiolhais et al. Comparison of computed theoretical values with experimental results is made and discussed. A reasonable agreement is found between our results and experimental data.
