We present the results of a search for supersymmetry with
gauge-mediated breaking and chi-tilda0_1 --> gamma G-tilda in the gamma
gamma + missing transverse energy final state. In 2.6 +/- 0.2 fb-1 of p
anti-p collisions at s**(1/2) ñ.96 TeV recorded by the CDF II detector we
observe no candidate events, consistent with a standard model background
expectation of 1.4 +/- 0.4 events. We set limits on the cross section
at the 95% C.L. and place the world's best limit of 149 GeV/c2 on the
chi-tilda0_1 mass at tau_{chi_tilda0_1} << 1 ns. We also exclude
regions in the chi-tilda0_1 mass-lifetime plane for tau_{chi-tilda0_1}
< 2 ns.
