    "abstract": "We study quantum mechanical systems with \"spin\"-related contact interactions\nin one dimension. The boundary conditions describing the contact interactions\nare dependent on the spin states of the particles. In particular we investigate\nthe integrability of $N$-body systems with $\\delta$-interactions and point spin\ncouplings. Bethe ansatz solutions, bound states and scattering matrices are\nexplicitly given. The cases of generalized separated boundary condition and\nsome Hamiltonian operators corresponding to special spin related boundary\nconditions are also discussed.",
