Results are presented from studies of the inclusive photon spectra in hadronic decays of the UPSILON' and UPSILON and the exclusive channel UPSILON' ..-->.. ..gamma gamma..UPSILON ..-->.. ..cap alpha cap alpha..l/sup +/l/sup -/, by the Crystal Ball detector at DORIS II. We measure two signals in the UPSILON' ..-->.. ..gamma.. + anything inclusive channel at E(..gamma..) == 108.3 +- 0.9 +- 3.0 MeV and at E(..gamma..) == 127.5 +- 1.2 +- 4.0 MeV. Branching ratios obtained for these signals are: BR(UPSILON' ..-->.. ..gamma..(108) + anything) == (6.3 +- 1.3 +- 1.4)% BR(UPSILON' ..-->.. ..gamma..(128) + anything) == (6.0 +- 1.3 +- 1.4)%.
