%X We present a phenomenological analysis of the 羽+羽- photoproduction data obtained by the CLAS collaboration at the Thomas Jefferson Laboratory. A special emphasis is put on the interference pattern observed in the moments of angular distribution for the 羽+羽- efective masses around 1 GeV. This pattern is attributed to the photoproduction of the scalar-isoscalar resonance f0(980). By fitting the model parameters to the data we obtain the strengths of the resonant and nonresonant parts of the S-wave photoproduction amplitude. We calculate the f0(980) photoproduction cross section which is smaller than previous estimations by a factor of about 5. A new estimation of the product of the 考 meson couplings to nucleon and to the 污老 system |gNN考g污老考| is given.
