Abstract

The optical potential approach for low-energy scattering of η mesons on three-body nuclei is compared to an exact treatment of the η 3N system using four-body scattering theory with eparable interactions in s waves only. The higher-order terms including the interaction of the struck nucleon with the surrounding nuclear medium and virtual target excitations in between successive η scatterings are found to cause important corrections. Effects of final state interaction in η photoproduction on 3H and 3He are also studied and sizable contributions beyond the optical model approach are found.
