    "abstract": "The Kohn variational principle and the (correlated) Hyperspherical Harmonics\ntechnique are applied to study the n-3H and p-3He scattering at zero energy.\nPredictions for the singlet and triplet scattering lengths are obtained for\nnon-relativistic nuclear Hamiltonians including two- and three-body potentials.\nThe calculated n-3H total cross section agrees well with the measured value,\nwhile some small discrepancy is found for the coherent scattering length. For\nthe p-3He channel, the calculated scattering lengths are in reasonable\nagreement with the values extrapolated from the measurements made above 1 MeV.",
