We use the CLEO detector at the Cornell e{sup +}e{sup {minus}} storage ring, CESR, to search for the two-photon production of the glueball candidate f{sub J}(2220) in its decay to K{sub s}K{sub s} . We present a restrictive upper limit on the product of the two-photon partial width and the K{sub s}K{sub s} branching fraction, ({Gamma}{sub {gamma}{gamma}}B{sub K{sub s}K{sub s}}){sub f{sub J(2220) }} . We use this limit to calculate a lower limit on the stickiness, which is a measure of the two-gluon coupling relative to the two-photon coupling. This limit on stickiness indicates that the f{sub J}(2220) has substantial glueball content. {copyright} {ital 1997} {ital The American Physical Society}
