Abstract
We consider dynamical spin-spin correlation functions in the one-dimensiona l repulsive half-filled Hubbard model. We propose an exact expression for t he two-spinon form factor of spin operators. We use this to derive the two- spinon contribution to the dynamical structure factor. [S0163-1829(99)02703 -4].
