WebDec 1, 2024 · The Buckingham potential is the most commonly used potential for describing atomic interactions in ionic materials. It mainly contains the repulsive term and the attractive term. The former degrades exponentially as the radial distance r increases, and the latter depends on r 6. WebWhere: POT_A_DEFN - this is the potential definition for the starting-potential. This is typically a potential-form label followed by potential parameters (see [Pair] section).; R_DETACH - detachment-point (note: as this is a multi-range potential definition the inclusive form >=R_DETACH is also valid).; SPLINE_DEFN - the type of spline to be …
