WebBorn-Mayer Equation! Born-Landé values are approximate.! Mayer showed that e–r/ρ, where ρ is a constant dependant on the compressibility of the crystal, gives a better repulsion term than 1/rn.! Using this improved repulsion term leads to the Born-Mayer equation: • ρ = 30 pm works well for all alkali metal halides and other simple
