Abstract
The S-wave phase shift δ(E) for the spin-doublet nd scattering at low energy E is calculated in the framework of the two-body approach. The effective-range-theory formula k cot δ = (1+k 2/k 20 )−1(−1/α+C 2 k 2+C 4 k 4) is used to obtain approximate analytical results with different potentials. The corresponding coefficients C 2 and C 4 are obtained from our previous calculations of the asymptotic normalization parameter function C 2t (aκ), where κ is the triton wave number and a is the doublet nd scattering length. The model reasonably describes δ(E), the results being quite sensitive to the choice of the effective nd potential.
