Asymptotic expansions are obtained for the scattering length a/sub 3//sub ///sub 2/ and the effective range r/sub 3//sub ///sub 2/ for the quartet state of three nucleons in the form of series in powers of the two-nucleon triplet effective range r/sub 0t/. This allows a model-independent description of these parameters and of the quartet phase shift of nd scattering in the effective-range approximation. Correlations between the parameters of three- and two-nucleon scattering are proposed and explained; these correlations allow the systematization of numerical calculations of a/sub 3//sub ///sub 2/ and r/sub 3//sub ///sub 2/ for different forms of interaction potentials. The influence of the energy dependence of the interaction on a/sub 3//sub ///sub 2/ is also considered.
