Abstract

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