Abstract: The general solution to the reflection equation associated with the jordaniandeformation of the SL2 invariant Yang R-matrix is found. The same K-matrix isobtained by the special scaling limit of the XXZ-model with general boundaryconditions. The Hamiltonian with the boundary terms is explicitly derivedaccording to the Sklyanin formalism. We discuss the structure of the spectrumof the deformed XXX-model and its dependence on the boundary conditions.
