Аннотация:Abstract—A method is discussed for determining the asymptotic normalization coefficients (ANC) usingthe analytic continuation of experimental differential cross sections for nuclear transfer reactions to thepole point of the reaction amplitude with respect to the variable cos θ, where θ is the scattering angle.Within the framework of this method, using experimental data on the differential cross section for thereaction 12C(0+; 0 MeV)(d, p)13C(1/2+; 3.09 MeV) the ANC for the channel 13C(1/2+; 3.09 MeV) →12C(0+; 0 MeV)+n was determined. When determining the ANC, the corrections caused by the Coulombinteraction in the initial, final and intermediate states of the reaction were taken into account. It is shownthat these corrections significantly affect the extracted ANC value.
