The K0s K0s Final State in Two-Photon Collisions
and Glueball Searches


The K0s K0s final state in two-photon collisions is studied with
the L3 detector at LEP using data collected
at centre-of-mass energies from 91 GeV
to 202 GeV. The mass spectrum is dominated
by the formation of the f'_2(1525) tensor meson 
in the helicity two state.
Clear evidence for destructive f_2-a_2 interference is observed.
In addition the signal for f_J(1750) is observed.
The study of the decay angular distribution of this state 
favours the spin two assignment.
No signal has been observed in the region around 2.2 GeV. An upper limit for
the two-photon partial width of the csi(2220) glueball candidate 
is derived.
