DOIAbstract
The photoproduction of omega mesons on LH<sub>2</sub>, C and Nb has been measured for incident photon energies from 900 to 1300MeV using the CB/TAPS detector at ELSA. The omega lineshape does not show any significant difference between the LH<sub>2</sub> and the Nb targets. The experiment was motivated by transport calculations that predicted a sensitivity of the omega lineshape to in-medium modifications near the production threshold on a free nucleon of Egamma<sup>lab</sup> = 1109MeV. A comparison with recent calculations is given
