Abstract
A fermion model consisting of two chains with interchain tunneling is formulated and solved exactly by the Bethe-ansatz method. The intercha in tunneling leads to Cooper-pair-like bound states and a threshold en ergy is required to overcome the binding energy. The correlation funct ions manifest superconducting properties.
