Given that the London dispersion interaction between two atoms or molecules has that general form \(V(r)= -(3/2) (I_{A}I_{B}/I_{A}+I_{B}) (\alpha_{A}\alpha_{B}/(4\pi\epsilon_{0})^{2}) (1/r^{6})\) and assuming that at long range only the \(r^{-6}\) "tail" of the Lennard-Jones potential is relevant, use the Lennard-Jones potential to estimate the ionization energy I of Kr if the polarizability volume \(\alpha/4\pi\epsilon_{0}\) is 2.48X10^-30m^3. Compare this value with the accepted value.
