A coupled channel model is used to study the nature of the scalar mesons
produced in the decay phi - gamma pi pi. The KKbar molecular picture of f0(980)
is found to be in a good agreement with the recent experimental data from SND
and CMD-2. The structure of the light scalar mesons is elucidated by
investigating the S-matrix poles and the qqbar spectral density.
