摘要

In-medium effects in photon excitation of the S_(11) resonance from nucleon and its decay to η-meson using the RMF approach is studied. We examine the in-medium effects by varing the Dirac fields of the nucleon and the S_(11) resonance separately. We obtained a conclusion that the Dirac fields of the nucleon, which reduces the nucleon effective mass, enlarge the width of S_(11) resonance, and small Dirac-fields of the resonance shifts the peak position, and these combined effects can explain the in-medium properties observed in the experimental data for~(12)C(γ,η) reaction.
