The scattering of a compound particle by a bound system in the case of weak interaction is considered. The Born cross‐sections for positronium and muonium scattering by a polar nonmagnetic medium were expressed by the complex permittivity function ε αß ( q , ω). The possibility of an experimental study of the frequency and wave vector dependence of the permittivity of homogeneous isotropic media using data on the scattering of leptonic atoms with spin transitions is investigated. The determination of Im {1/ε ∥ ( q , ω)} by small‐angle thermal scattering data is also discussed.
