A new expression for the Anderson-Grüneisen parameter δ for ionic crystals

The Anderson-Grüneisen parameter δ has been computed theoretically from a general expression developed by Sharma and Tripathi6]. The δ-γ (Grüneisen parameter) curves have been plotted to find a relation for the best fitted yielding curves by the method of least squares. The relation developed can be put as δ = AγB and it can be inferred that chang's3] relation is a particular case of this general equation.
