Multipole analysis of deuteron photodisintegration at photon energy up to 600 MeV

The multipole analysis of the γd → pn process is carried out on the basis of experimental data on dσ/dΩ, Σ asymmetry, proton polarization of P and T asymmteries caused by deuteron vector polarization at photon energy from 250 to 600 MeV (2.11 ≤ √S ≤ 2.40 GeV). The deuteron photodisintegration amplitudes are determined by contributions of three parts: a set of gradient-invariant pole amplitudes taking into account the deuteron structure, phenomenological amplitudes of pion photoproduction on nucleons and dibaryon resonances. It is shown that the x2/df functional depends on sets of dibaryon resonances much stronger than on the used deuteron wave functions
