Abstract
We consider the three-particle scattering S-matrix for the Landau-Lifshitz model by directly computing the set of the Feynman diagrams up to the second order. We show, following the analogous computations for the non-linear Schrödinger model, that the three-particle S-matrix is factorizable in the first non-trivial order.
