A study of various bottomonium states, in Y(2S)-> gamma (b b-bar) decays, reconstructed exclusively in 26 hadronic final states is presented. The study is performed using a data sample recorded at the Y(2S) resonance with the Belle detector at KEKB, that contains 157.8 X 106 Y(2S) events. The chibJ(1P) states are found with their masses being consistent with the world average values. We find no evidence for the state claimed to have been observed around 9975 MeV/c2 in an analysis based on a data sample of 9.3 X 106 Y(2S) events collected with the CLEO~III detector, and place an upper limit an order of magnitude lower than the latter result. In the same study, the etab(1S) state is also searched for.
