The scalar products and the norm of Bethe eigenstates for the boundary XXX Heisenberg spin-1/2 finite chain Original Research Article

For the XXX Heisenberg spin-12 finite chain with integrable open boundary, the scalar products and the norm of Bethe eigenstates are computed directly in the F-basis. The results are represented as determinants of usual functions of the parameters of the model. The Gaudin formula for the square of the norm of the Bethe wave functions is proved for the case of integrable open boundary condition.
