  ABSTRACT: The photoproduction of w \omega mesons on LH2 , C and Nb has been measured for incident photon energies from 900 to 1300MeV using the CB/TAPS detector at ELSA. The w \omega lineshape does not show any significant difference between the LH2 and the Nb targets. The experiment was motivated by transport calculations that predicted a sensitivity of the w \omega lineshape to in-medium modifications near the production threshold on a free nucleon of Eglab=1109\ensuremath{E_{\gamma}^{lab}=1109} MeV. A comparison with recent calculations is given.

  ABSTRACT: 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.}
