摘要：

A rigid‐ion Lundqvist many‐body potential model is used to derive expressions of the second‐order elastic (SOE) constants and the principal Raman frequency for solids crystallizing in the fluorite structure. Application to CaF2, SrF2, and BaF2 clearly demonstrates the inadequacy of the Born potential and the importance of three‐body interactions in this system.
