    Paper

    The photoproduction of \(\omega\) mesons on LH_2, C and Nb has been studied for incident photon energies from 900 to 1300 MeV using the CB/TAPS detector at ELSA. The \(\omega\) line shape does not show any significant difference between the LH_2 and the Nb targets. The data are compared with results of transport calculations that predict a sensitivity of the \(\omega\) line shape to in-medium modifications near the production threshold on a free nucleon of \(E_{\gamma}^{lab}\) = 1109 MeV.}
