Abstract
Quasifree photoproduction of mesons off nucleons bound in the deuteron has been measured with the CBELSA/TAPS detector for incident photon energies up to 2.5 GeV at the Bonn ELSA accelerator. The mesons have been detected in coincidence with recoil protons and recoil neutrons, which allows a detailed comparison of the quasifree and reactions. The excitation function for production off the neutron shows a pronounced bumplike structure at (), which is absent for the proton.
