Abstract

A model-independent description of the phase shift of the elastic nd-scattering in the quartet state is grounded, and explicit solutions for the low-energy scattering parameters (the quartet scattering length a3/2 and effective range r3/2) are obtained in the form of asymptotically exact expansions in terms of the ratio of the experimental two-nucleon low-energy scattering parameters.
