- Аннотация: Asymptotic normalization coefficients (ANC) are important nuclear characteristics. This paper discusses a method for determining ANC values from experimental data on differential cross-sections of nuclear transfer reactions. The method is based on the use of the analytic continuation of these cross-sections to the pole point of the reaction amplitude with respect to the variable cosθ, where θ is the center-of-mass scattering angle. The method under consideration is used to determine the ANC for the channel 17O(1/2+; 0.871MeV) →16O(0+; 0MeV) +n from the data on the 16O(0+; 0MeV)(d,p)17O (1/2+; 0.871MeV) reaction. When determining the ANC, the corrections caused by the Coulomb interaction in the initial, final and intermediate states of the reaction were taken into account. It is shown that these corrections have a great impact on the extracted ANC value.
