- Аннотация: A model for the NN force, which is induced by the formation of an intermediate dibaryon dressed with σ- and other meson fields, has been developed by the present authors in previous years. This model is applied to the deuteron photodisintegration processes with the main focus on the γ-induced polarization Py' of the neutron at energies below Eγ≲ 30 MeV. The inclusion of the intermediate dibaryon leads to a model of the NN force completely different to the conventional NN potential models at short distances. Here the model is tested on the nucleonic level through comparison to rather similar predictions from the conventional NN potential model both for the total and differential cross sections and also for the spin polarization of the ejected neutrons. The predictions of the present model are at least of the same quality than those for the Nijmegen potential; the visible differences with experimental data for Py' still remain. However, in combination with the previous results a consistent description can be achieved simultaneously for many observables.
