SCHEDULED MAINTENANCE:
A new theoretical model of potential-energy functions for atomic solids has been developed. An angular factor has been included in this model and its effect has been discussed. Using this new model a new preliminary potential for silicon crystal has been derived. The calculated phonon dispersion curve along the [q00] direction, using this new potential, has been given. A good agreement has been found with experiment.
