Abstract
Based on events collected with the BABAR detector, we have observed the bottomonium state through the decay chain. The significance for the member of the triplet is 5.8 standard deviations including systematic uncertainties. The mass of the state is determined to be . We use the invariant mass distribution to confirm the consistency of the observed state with the orbital angular momentum assignment of the .
