    "abstract": "A distinct isotopic effect in phi photoproduction at 2-5 GeV region is\nidentified by examining the production amplitudes due to Pomeron-exchange and\nmeson-exchange mechanisms. This effect is mainly caused by the pi-eta\ninterference constrained by SU(3) symmetry and the isotopic structure of the\ngamma NN coupling in the direct phi-radiation amplitude. It can be tested\nexperimentally by measuring differences in the polarization observables between\nthe gamma-p and gamma-n reactions.",
