Аннотация:A new method is proposed for extrapolation of elastic-scattering data to the negative-energy region for a short-range interaction. The method is based on the analytic approximation of the modulus-squared of the partial-wave scattering amplitude and can serve as an alternative to the traditional one based on continuation of the effective-range function. The new method has been applied to determine the asymptotic normalization coefficients for the 17O and 13C nuclei in the n+16O and n+12 C channels, respectively. The asymptotic normalization coefficients obtained by the new method are compared with the ones obtained in the effective-range function approach.
