Abstract
Using an interchange theorem the polarizability of the neon atom at imaginary frequencies is calculated correct to first order in electron correlation. These results are then used to evaluate the long‐range dispersion interactions between two neon atoms and between neon and helium atoms. For neon‐neon interactions we find , while for neon‐helium we find .
