Abstract The Crystal Ball detector at thee + e − storage ring DORIS-II has been used to search for radiativeB meson decays, especially of the typeb→sγ. No monoenergetic γ-lines have been found in the inclusive photon spectrum from У(4S) decays, and upper limits are obtained for radiative decays ofB mesons to various strange mesons and to theD *. Integrating the photon spectrum over the corresponding energy range, we find $$BR(B \to \gamma X)〈 2.8 \times 10^{ - 3} ,$$ at 90% confidence level for the mass range 892 MeV ≦M X ≦2045 MeV.
