The Three-Nucleon System Near the N-d Threshold

Nuclear Theory 2009-10-30 v1 Nuclear Experiment

Abstract

The three-nucleon system is studied at energies a few hundred keV above the N-d threshold. Measurements of the tensor analyzing powers T20T_{20} and T21T_{21} for p-d elastic scattering at Ec.m.=432E_{c.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 D- to S-state ratio for 3^3H and 3^3He, for which recent experimental results are available, is also presented.
