Title:Resonance Formation in Two-Photon Collisions at LEP 
in the K0_S, K+-pi-+ and eta ,pi+pi- final states


The K0_S, K+-pm pi-+ and eta,pi+pi- final states 
in two-photon collisions 
are studied with the L3 detector at LEP using data collected
at centre-of-mass energies from 183 to 202 GeV. 
The mass spectrum  of the K0_S, K+-pi-+ final state is analyzed 
from threshold to 2 GeV.
A peak in the mass spectrum  
may be identified with the eta (1440) resonance.
This resonance is observed in gamma-gamma collisions for the first time.
This state is not observed in the eta,pi+,pi- decay mode. 
The product of the two-photon width of eta(1440) 
and the branching ratio to
K0_S, K+-pi-+ decay channel is measured and the upper limit of that 
for eta,pi+pi-
decay channel is given. The hypothesis that the eta (1440) is 
gluonium state is examined.
