Abstract
Properties of the S11(1535) resonance in nuclear medium were investigated through the 12C(γ,η) reaction for photon energies between 0.68 and 1.0 GeV. A broad resonance due to the the S11 excitation in the carbon nucleus was clearly observed for the first time. The data were compared with calculations of the quantum molecular dynamics, and the observed shape being different from the elementary one is essentially explained by the medium effects such as the Fermi motion, the Pauli blocking and effects of N–η and N–N∗ collisions.
