• Аннотация: The problem of analytic continuation of the scattering data to the negative-energy region to obtain information on asymptotic normalization coefficients (ANCs) of bound states is discussed. It is shown that a recently suggested Δ method [O. L. Ramírez Suárez and J.-M. Sparenberg, Phys. Rev. C 96, 034601 (2017)] is not strictly correct in the mathematical sense since it is not an analytic continuation of a partial-wave scattering amplitude to the region of negative energies. However, it can be used for practical purposes for sufficiently large charges and masses of colliding particles. Both the Δ method and the standard method of continuing of the effective range function are applied to the p−16O system, which is of interest for nuclear astrophysics. The ANCs for the ground 5/2+ and excited 1/2+ states of 17F are determined.
