The Anderson-Grüneisen Parameter for Some Diatomic Crystals

Abstract

The general equation for Anderson-Grüneisen parameter δ developed by Sharma and Tripathi (Phys. Letters A39 (1972) 281) has been tested theoretically by computing the δ values for bcc and fcc types of ionic crystals employing the central force rigid ion interaction model. Furthermore, the Anderson-Grüneisen parameter has also been calculated from two relations of Chang. The dilemma confronted by Chang, regarding the correctness of these two relations for δ has been resolved.
