Photoproduction of $\eta$-mesons off C and Cu nuclei for photon energies below 1.1 GeV

T. Kinoshita, H. Yamazaki, H. Fukasawa +40

The $\eta$-meson photoproduction cross sections have been measured on the C and Cu targets for the photon energies between 600 and 1100 MeV to investigate the behavior of the $S_{11}$…
