### Abstract

A procedure is considered for extracting the purely nuclear scattering length a_{s} and effective range r_{s} (which correspond to a strong-interaction potential V_{s} with disregarded Coulomb interaction) from the experimentally determined nuclear quantities a_{cs} and r_{cs}, which are modified by Coulomb interaction. The Coulomb renormalization of a_{s} and r_{s} is especially strong if the system under study involves a level with energy close to zero (on the nuclear scale). This applies to formulas that determine the Coulomb renormalization of the low-energy parameters of s scattering (l = 0). Detailed numerical calculations are performed for coefficients appearing in the equations that determine Coulomb corrections for various models of the potential V_{s}(r). This makes it possible to draw qualitative conclusions about the dependence of Coulomb corrections on the form of the strong-interaction potential and, in particular, on its small-distance behavior. A considerable enhancement of Coulomb corrections to the effective range r_{s} is found for potentials with a barrier.
