New boundary bound states (BBS) are found of an integrable model with themagnetic impurities located at the edges of an open Heisenberg spin chain.These bound states carry the real energy and are formed by three or fiveimaginary modes of the rapidities. These imaginary modes of the rapidities givethe non-zero antisymmetric wave functions and the moments of the centers of thebound states are zero. It means that these bound states are arisen by themagnetic impurities and localized at the edges of the correlated system. TheKondo screening occurs for the antiferromagnetic spin chain with theferromagnetic impurities-electrons exchange interaction.Comment: 4 pages, Revte
