Using 13.3 fb-1 of e+e- data recorded with the CLEO II and CLEO II.V detector configurations at CESR, we have searched for fJ(2220) decays to KS0KS 0 in untagged two-photon interactions. We report an upper limit on the product of the two-photon partial width and the branching fraction, ΓγγΒ(fJ(2220)→K S0KS0, of less than 1.1 eV at the 95% confidence level; systematic uncertainties are included. This data set is four times larger than that used in the previous CLEO publication.
