【 摘 要 】

Differential cross sections of the gamma + d -> d + pi(up 0) reaction were measured at photon beam energies between 0.5 and 2.0 GeV over a wide angular range in CM system. The experiment was performed in Hall B at Jefferson Lab using the CLAS detector. The excitation function, especially at backward CM scattering angles, has been studied with regard to effects due to intermediate on-shell eta and omega rescattering. At CM scattering angles greater than 123 deg our data clearly show an enhancement around 0.7 GeV, which could be attributed to an intermediate on-shell eta-state.
