Abstract: The emittance growth due to intrabeam scattering (IBS) depends on the scattering cross section and is therefore affected by the exchange interaction of identical particles. However, as the IBS growth rates are typically dominated by small-angle scattering events and the exchange interaction only significantly alters the cross section at relatively large angles, the influence of the exchange interaction is usually small. In this paper, we calculate the small corrections to the growth rates resulting from the exchange interaction. We include the polarization dependence of the exchange term in the cross section, and so we also present the growth rates as a function of the beam polarization.
