Abstract

The results of linear regresion of differential cross sections, Σ- and T-asymmetries of η-photoproduction on protons in energy region from threshold up to 1 GeV are presented. Serious contradictions between angular distributions measured in different laboratories are revealed. The energy dependance of regression coefficients may be due to transition from energy region of S₁₁(1535) and D₁₃(1520) to energy region of D₁₅(1675) and F₁₅(1680) resonances.
