The observations for the hadronic decays of the bottomonium states were discussed. Hadronic transitions proceeded by the emission of low momentum gluons and subsequent hardronization of the gluons. Photons were detected using an electromagnetic calorimeter which consisted of 7784 Csl (TI) crystals. It was observed that the ratio of the measured branching ratios for the two transitions were in agreement with theoretical expactations based on S wave phase space factors for multipole expansions.
