Abstract

Using a (Formula presented) data sample collected with the CLEO II detector at the Cornell Electron Storage Ring, we have searched for dipion transitions between pairs of Υ resonances at center of mass energies (Formula presented) and (Formula presented) We obtain the 90% confidence level upper limits (Formula presented) and (Formula presented) We also observe the transitions (Formula presented) (Formula presented) and (Formula presented) from which we measure the cross sections for the radiative processes (Formula presented) and (Formula presented) We obtain (Formula presented) and (Formula presented) at (Formula presented) and (Formula presented) and (Formula presented) at (Formula presented) which we compare with theoretical predictions. © 1999 The American Physical Society.
