In this work, we investigate the production of Xb in the process Υ(5S,6S)→ γXb, where Xb is assumed to be the counterpart of X(3872) in the bottomonium sector as a B B^* molecular state. We use the effective Lagrangian based on the heavy quark symmetry to explore the rescattering mechanism and calculate their production ratios. Our results have shown that the production ratios for the Υ(5S,6S) → γXb are orders of 10-5 with reasonable cutoff parameter range α≃ 2∼ 3. The sizeable production ratios may be accessible at the future experiments like forthcoming BelleII, which will provide important clues to the inner structures of the exotic state Xb.
