摘要：
The most general physical boundary S-matrix for the open XXZ spin chain in the non-critical regime (cosh(eta) > 1) is derived starting from the bare Bethe ansatz equations. The boundary S-matrix as expected is expressed in terms of Gamma(q)-functions. In the isotropic limit the corresponding results for the open XXX chain are also reproduced.
