Abstract： A new theoretical model of potential energy functions for atomic solids is developed. An angular factor is included in this model and its effect is discussed. Using this new model, a new preliminary potential for silicon crystal is derived. Calculated phonon dispersion curves, using this new potential, is given. A good agreement has been found.
