We study the interaction between dark sectors by considering the momentum
transfer caused by the dark matter scattering elastically within the dark
energy fluid. Describing the dark scattering analogy to the Thomson scattering
which couples baryons and photons, we examine the impact of the dark scattering
in CMB observations. Performing global fitting with the latest observational
data, we get a constraint on the dark scattering between dark sectors.
