Integrated intensities of Bragg reflections were measured with a triple‐axis neutron spectrometer for powder samples of K x Rb 1− x Cl for x = 0.5. The temperature factors were corrected for thermal diffuse scattering (TDS) and static contributions. The Debye temperature and the mean temperature factors obtained from these measurements are compared with the values obtained by other techniques and are found to be in good agreement. The Debye temperatures for RbCl ( x = 0) and KCl ( x = 1) determined by other authors were combined with these results and the concentration dependence of Θ in K x Rb 1− x Cl, was found to be non‐linear.
