Abstract: (Elsevier)

We have measured the branching fraction of the inclusive radiative B meson decay B → X s γ to be Br ( B → X s γ )=(3.36±0.53(stat)±0.42(sys) +0.50 −0.54 (th))×10 −4 . The result is based on a sample of 6.07×10 6 B B ̄ events collected at the ϒ (4 S ) resonance with the Belle detector at the KEKB asymmetric e + e − storage ring.
