A　scheme　is　proposed　to　teleportation　of　an　unknown　multi-atom　entangled　state,　considering　the　entangled　states　of　two　or　more　particles　play　an　important　role　in　both　demonstrating　quantum　nonlocality　and　quantum　information　processing.　The　scheme　is　based　on　the　degenerate　Raman　interaction　of　a　Λ-type　three-level　atom　with　a　single-mode　field.　First　let　n　atoms　cross　a　coherent　cavity　field　in　succession　to　prepare　a　quantum　channel.　Then　the　sender　lets　the　other　n　atoms　which　carry　the　unknown　state　cross　the　cavity　in　succession　and　makes　a　joint　measurement　by　detecting　the　cavity　field　and　the　atoms　separately.　When　|α|＞＞1,　the　cavity　field　can　be　detected　with　the　measurement　method　of　detecting　orthogonal　states.　Finally　the　receiver　reconstructs　the　initial　state　according　to　the　outcome　of　the　joint　measurement　transmitted　through　a　classical　channel.　The　advantage　of　the　scheme　is　that　it　uses　an　entangled　state　of　a　coherent　state　with　n　atoms　as　a　quantum　channel,　which　makes　the　scheme　simple　and　easy.　The　scheme　is　expected　to　be　useful　in　demonstrating　quantum　nonlocality　and　information　processing.
