The three-nucleon system is studied at energies a few hundred keV above the N-d threshold. Measurements of the tensor analyzing powers T20 and T21 for p-d elastic scattering at Ec.m. = 432 keV are presented together with the corresponding theoretical predictions. The calculations are extended to very low energies since they are useful for extracting the p-d scattering lengths from the experimental data. The interaction considered here is the Argonne V18 potential plus the Urbana three-nucleon potential. The calculation of the asymptotic Dto S-state ratio for H and He, for which recent experimental results are available, is also presented. PACS numbers: 25.10+s,24.70.+s,21.45.+v key words: N-d scattering, polarization observables, effective range expansion, asymptotic constants
