We have sought evidence for radiative decays of neutralinos produced in proton-antiproton collisions at {radical}{ital s}=1.8TeV. Events containing two photons plus large missing transverse energy were investigated. The observed event rate and the missing transverse energy distribution of the two-photon events are consistent with QCD predictions. Inferred limits on squark and gluino masses depend on the supersymmetry model parameters. The particular choices {mu}={minus}40GeV/{ital c}{sup 2} and tan{beta}=1.5 lead to 90%-confidence-level asymptotic lower limits of 110 GeV/{ital c}{sup 2} and 140 GeV/{ital c}{sup 2} for squarks and gluinos, respectively.
