We calculated the coupled channel photoproduction amplitudes of the scalar isovector resononace a0(980), which include the πη, K+K− and K0K̅0intermediate states. Based on them we obtained the mass distribution in the πη channel at photon energy Eγ=7 GeV, corresponding to energy accissible in new JLab experiments CLAS12 and GlueX. We also analyzed the shape of mass distribution as a function of the phase of the background amplitude.
