Abstract

We calculate the doublet and quartet neutron-deuteron scattering lengths using a nonlocal nucleon-nucleon interaction fully derived from quark-quark interactions. We use as input the NN¹S₀ and ³S₁\text\ensuremath-³D₁ partial waves. Our result for the quartet scattering length agrees well with the experimental value but the result for the doublet scattering length does not. However, if we take the result for the doublet scattering length together with the one for the triton binding energy they agree well with the so-called Phillips line.
