N ov 2 00 1 ηN Final State Interaction in incoherent Photoproduction of η - mesons from the Deuteron near Threshold
An analysis of incoherent photoproduction of η mesons off the deuteron for photon energies from threshold to 800 MeV is presented. The dominant contribution , the γN-ηN amplitude, is described within an isobar model. Effects of the final state interactions in the N N as well as the ηN systems are included employing models derived within the meson-exchange approach. It is found that their consid...
متن کامل2 00 1 Incoherent Photoproduction of η - mesons from the Deuteron near Threshold
Incoherent photoproduction of the η-meson on the deuteron is studied for photon energies from threshold to 800 MeV. The dominant contribution, the γN-ηN amplitude, is described within an isobar model. The final state interaction derived from the CD-Bonn potential is included and found to be important for the description of the production cross section close to threshold. Possible effects from t...
متن کاملInfluence of final state interaction on incoherent η - photoproduction on the deuteron near threshold ∗
Incoherent η-photoproduction on the deuteron is studied for photon energies from threshold up to 720 MeV. The elementary γN → ηN amplitude is constructed in the frame of a conventional isobar model. Effects of final state interaction are investigated and their role in the cross section as well as in polarization observables is found to be important. Inclusion of such effects leads to a satisfac...
متن کاملThree - Body Analysis of Incoherent Photoproduction of η Mesons on the Deuteron near Threshold ∗
The importance of three-body dynamics in the ηnp system in elastic and inelastic η-deuteron scattering as well as coherent and incoherent η photo-production on the deuteron in the energy region from threshold up to 30 MeV above has been investigated. It is shown that a restriction to first order rescat-tering with respect to the N N-and ηN-final state interactions, i.e., restriction to rescatte...
متن کاملPhotoproduction of η ′ - mesons off the deuteron
Quasi-free photoproduction of η′-mesons off nucleons bound in the deuteron has been measured with the combined Crystal Barrel TAPS detector. The experiment was done at a tagged photon beam of the ELSA electron accelerator in Bonn for incident photon energies from the production threshold up to 2.5GeV. The η′-mesons have been detected in coincidence with recoil protons and recoil neutrons. The q...
