Abstract
A search has been made with the Crystal Ball Detector for axionlike particles in radiative decays. An upper limit on the branching ratio (90% C.L.) is obtained. This result holds for long-lived, noninteracting pseudoscalar or vector particles of mass less than 1 GeV. Thus, this experiment also places stringent limits on the existence of other possible light bosons such as those arising in supersymmetric theories.
