摘要：
It is found that the finite-energy spectral properties of the one-dimensional Hubbard model are controlled by the scattering of charged eta-spin-zero 2v-holon composite objects, spin-zero 2v-spinon composite objects, and charged eta-spinless and spinless objects, rather than by the scattering of independent eta-spin-1/2 holons and spin-1/2 spinons. Here v = 1, 2,.... The corresponding S matrix is calculated and its relation to the spectral properties is clarified.
