• The temperature variations of the Debye-Waller exponents for face-centred cubic metals copper, silver, gold, aluminium, and nickel have been investigated by using a modified non-central force model given by Behari and Tripathi (1969). The force model takes into account Clark, Gazis and Wallis type angular forces and also the effect of electron-ion interaction given by Sharma and Joshi. The results of calculations have been compared with the experimental data in terms of the Debye-Waller factor temperature parameter Y=log_<10>e.(λ/sin θ)^2(2W_<TO>-2W_T), the effective X-ray characteristic temperature 〓_M, and the mean square displacement of the atoms <u^2>^^-. The agreement between the theoretical values and the experimental results has been found reasonably satisfactory.
