Abstract: (arXiv)

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.}
