Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Coherent pi-photoproduction off the deuteron near _-threshold is investigated within an approach which includes the amplitudes of impulse approximation, two-step process with piN- and _N-rescattering, and intermediate _NN interaction. Results for unpolarized and polarized cross sections as well as for all possible polarization observables with polarized photons and/or oriented deuterons are predicted and compared with available data, and differences with other theoretical models are analyzed. The contribution of this reaction to the deuteron spin asymmetry is calculated and its contribution to the GDH integral is explicitly evaluated by integration up to a photon energy of 900 MeV. In addition, the sensitivity of the results to the elementary amplitude and the choice of the NN potential model governs the deuteron wave function is also investigated. This work is motivated by the measurements of the CLAS Collaboration at Jefferson laboratory, where a cusp-like structure in the energy dependence of the differential cross section has been observed at extremely backward pion angles. 88 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Incoherent pion photoproduction on the deuteron is investigated with inclusion of all leading NN effects. Formal expressions for polarization observables are derived and described by various beam, target and beam-target asymmetries for polarized photons and/or oriented deuterons. Results are given for unpolarized cross sections and all possible polarization observables with polarized photons and/or oriented deuterons. The contributions to the spin asymmetry and the Gerasimov-Drell-Hearn (GDH) integral from separate channels are evaluated by explicit integration up to a photon lab-energy of 350 MeV. Effects of final-state interaction are investigated and their role in these observables are found to be significant, specially for neutral-pion production. The extracted results are compared with available experimental data and predictions of other works, and a satisfactory agreement is obtained. We expect that the results presented in this book may be useful to interpret the recent measurements from the high-intensity and high duty-factor electron accelerators MAMI, ELSA, Jefferson Lab, LEGS, MAX-Lab, SPring-8, LNS, and GRAAL. 68 pp. Englisch. …
