INTERFERENCE IN THE REACTION E(-)-]GAMMA-PI(+)PI(-) AND THE SEARCH FOR THE DECAY PHI-]GAMMA-F(0)-]GAMMA-PI(+)PI(-)()E()

We describe the interference between amplitudes e(+)e(-)->gamma pi(+)p i(-) and e(+)e(-)->phi-->gamma f(0)-->gamma pi(+)pi(-), here the f(0) meson is considered in the framework of the four-quark model and the m odel of the scalar <K(K)over bar> molecule. The general expressions fo r the differential cross section with the radiative corrections and tw o angle cuts are given. The interference patterns are obtained in tile spectrum of the differential cross section by the energy of the photo n and in the full cross section by the energy of the beams.
