The original model of Das et al. is modified in extending the electron-ion interaction on a three-body forces and including the crystal equilibrium con­dition to reduce one independent parameter. We studied the phonon dis­persion relations along the three principal symmetry directions i.e. [ξ,0,0], [ξ,ξ,0] and [ξ,ξ,ξ] and θ-T curves of alkali metals, Na, K, Rb, Cs and Li. There is close agreement between the computed results and the experimental observations.
