  We have analyzed the K+K- photoproduction on hydrogen in the effective mass
region around the mass of the phi(1020) meson. The interference of the S-wave
contribution with the P-wave has been studied. Both scalar resonances f0(980)
and a0(980) have been taken into account. We have obtained a good description
of the available experimental data, in particular the mass distributions and
the moments of the kaon angular distribution. Our calculations give values of
the integrated S-wave total photoproduction cross section between 4 and 7 nb
for the K+K- effective mass range around the phi(1020) mass and at the
laboratory photon energy near 5 GeV. These numbers favor lower experimental
estimates obtained at DESY.
