POLARIZATION EFFECTS IN THE AGBR INTERACTION POTENTIAL

A pairwise additive interaction potential (including a shell model to account for ion polarizabilities) was developed for describing crystal line AgBr. It was constructed by fitting experimental data, including lattice constant, phonon frequencies at the Gamma and X points, dielec tric constant, cohesive energy, and elastic constants. The predicted r esults compare favorably with experimentally measured values. The infl uence of polarization effects on the various crystal properties is dis cussed.
