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 crystalline AgBr. It was constructed by fitting experimental data, including lattice constant, phonon frequencies at the Γ and X points, dielectric constant, cohesive energy, and elastic constants. The predicted results compare favorably with experimentally measured values. The influence of polarization effects on the various crystal properties is discussed.
