N2 - We compute by Bethe Ansatz both bulk and boundary hole scattering matrices for the critical Ascript N sign-1(1) quantum spin chain. The bulk S matrix coincides with the soliton S matrix for the Ascript N sign-1(1) Toda field theory with imaginary coupling. We verify our result for the boundary S matrix using a generalization of the Ghoshal-Zamolodchikov boundary crossing relation.
