The reaction e+e →e+eγ∗γ∗→e+e K0SK0S is studied with the L3 detector at LEP and the formation of the f2'(1525) resonance is observed. For an integrated luminosity of 114 pb−1, 31±6 f2' events are found. Their angular distribution is consistent with a pure helicity two. The radiative width times the branching ratio is measured to be Γγγ(f'2) × (Br((f'2→ KK̅)keV. Only three events are found in the f2(1270)-a2(1320) mass region, consistent with destructive f2-a2 interference in the KS0KS0 final state. The mixing angle of the tensor meson nonet is determined to the θ = (29.4−1.6+1.4)±.
