  "abstract": "New mechanism for the observed inclusive B -> \\eta'X decay is suggested. We argue that the dominant contribution to this amplitude is due to the Cabbibo favored b -> \\bar{c}cs process followed by the transition \\bar{c}c -> \\eta'. A large magnitude of the \"intrinsic charm\" component of \\eta' is of critical importance in our approach. Our results are consistent with an unexpectedly large Br(B -> \\eta'+X) \\sim 10^{-3} recently announced by CLEO. We stress the uniqueness of this channel for 0^{-+} gluonia search.",
