Radiative decays of the upsilon (2S) resonance
[report]
1984
unpublished
Preserved Fulltext
The Crystal Ball Detector at DORIS II was used to study radiative decays of the T( 2s) resonance with more than twice the previously available data The inclusive photon spectrum of hadronic T(2S) decays and the exclusive channel T(2S) + mT(lS) 4 77 @e were analysed. In the inclusive spectrum three significant photon lines at energies of Eqr = (108.2 f 0.7 f 4)
