We obtained the relations for the amplitudes of the E1→⁵P₁, M1→⁵D₁, E2→⁵D₂-transitions at the two-cluster (α-⁸Ве(2⁺)) photodisintegration of the ¹²C nucleus from the analysis of the experimental data for ∑(90º)-asymmetry and the α-particle angular distributions in the reaction ¹²C(γ,α) at energies of the linearly polarized photons 15.8-33.5 МeV.
