Abstract
In the reaction γγ→K 0S K 0S resonance production of thef −2 is observed. For the radiative with\(\Gamma _{\gamma \gamma } .B(f'_2 \to K\bar K) = 0.11_{ - 0.02}^{ + 0.03} \pm 0.02keV\) is found. The small number of events in thef 2,a 2 mass region is consistent with the assumption of destructivef 2−a 2 interference. From the mass distribution we determine the relative phases between the tensor mesons. Upper limits on the radiative widths of the glueball candidatesf 2(1720) andX (2220) are derived.
