Abstract
The most general physical boundary -matrix for the open XXZ spin chain in the non-critical regime () is derived starting from the bare Bethe ansazt equations. The boundary -matrix as expected is expressed in terms of -functions. In the isotropic limit corresponding results for the open XXX chain are also reproduced.
