| Özet: | Incoherent pion photoproduction on the deuteron is studied in the first resonance region. The unpolarized cross section, the beam asymmetry, and the vector and tensor target asymmetries are calculated in the framework of a diagrammatic approach. Pole diagrams and one-loop diagrams with NN scattering in the final state are taken into account. An elementary operator for pion photoproduciton on the nucleon is taken in various on-shell forms and calculated using the SAID and MAID multipole analyses. Model dependence of the obtained results is discussed in some detail. A comparison with predictions of other works is given. Although a reasonable description of many available experimental data on the unpolarized total and differential cross sections and photon asymmetry has been achieved, in some cases a significant disagreement between the theory and experiment has been found. Invoking known information on the reactions γd→π0d and γd→np the authors predict the total photoabsorption cross section for deuterium. The authors find that the values strongly overestimate experimental data in the vicinity of the Δ peak В фонде НТБ ТПУ отсутствует |
