A new one-dimensional fermion model depending on two independent interactionparameters is formulated and solved exactly by the Bethe ansatz method. TheHamiltonian of the model contains the Hubbard interaction and correlatedhopping as well as pair hopping terms. The density-density and paircorrelations are calculated which manifest superconducting properties incertain regimes of the phase diagram.Comment: 8 pages, latex, 2 postscript figure
