Abstract

Using the CsI calorimeter of the CLEO-II detector, we have studied exclusive radiative decays of the Υ{hooked}(3S) to the (2P) states where the final state consists of two photons and two leptons (e e or μ μ , from either the Υ{hooked}(1S) or Υ{hooked}(2S)). We observe and measure branching ratios for the J=2 and J=1 (2 P ) states, and set upper limits for the J=0 state. © 1992. χ χb J + - + - 3
