    "abstract": "The diffractive $\\phi$-meson photoproduction amplitude is dominated by the\nPomeron exchange process and contains the terms that govern the spin-spin and\nspin-orbital interactions.\n  We show that these terms are responsible for the spin-flip transitions at\nforward photoproduction angles and appear in the angular distributions of\n$\\phi\\to K^+K^-$ -decay in reactions with unpolarized and polarized photon\nbeams.\n  At large momentum transfers, the main contribution to the $\\phi$-meson\nphotoproduction is found to be due to the excitation of nucleon resonances.\n  Combined analysis of $\\omega$ and $\\phi$ photoproduction indicates strong\nOZI-rule violation in $\\phi NN^*$ - couplings.\n  We also show that the spin observables are sensitive to the dynamics of\n$\\phi$-meson photoproduction at large angles and could help distinguish\ndifferent theoretical models of nucleon resonances.\n  Predictions for spin effects in $\\phi$-meson photoproduction are presented\nfor future experimental tests.",
