|Abstract:||The effect of high pressure over the structural stability of silver iodide (AgI) has been investigated. The structural properties of silver iodide have been calculated using Two Body Potential Model, comprising of Long-Range (L-R) Coulomb and van der Waals interactions and Short-Range (S-R) Hafemeister Flygare (HF) type overlap repulsive interactions. The phase transition pressure (Pt) and relative volume collapse Δ[V(Pt)/V(O)] as a function of pressure calculated by us for zinc-blende (B₃) and tetragonal (BT) structure are found to be in good agreement with the available experimental data.|
