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+k2/k 0 2 )?1(?1/α+C2k2+C4k4) is used to obtain approximate analytical results with different potentials. The corresponding coefficients C2 and C4 are obtained from our previous calculations of the asymptotic normalization parameter function C t 2 (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. |
