Abstract

Evidence is reported from the CLEO detector for the b (1P) states from radiative decays of the ' (2S). Photons are detected by pair conversion in the beam pipe or a lead radiator, and the pair momenta are measured in the drift chamber. Two photon lines are well resolved, with energies 109.50.71 and 129.00.81 MeV.
