摘要：
Diffractive photoproduction of phi mesons near threshold involves Pomeron exchange, pseudoscalar exchanges and possible exotic components such as glueball and scalar-meson exchange. We measured phi-meson photoproduction from protons and deuterons at forward angles by using linearly polarized photons with E-gamma = 1.5-2.4 GeV. The decay asymmetries show dominance of the natural-parity exchange process. The energy dependence of cross sections will help in determining the behavior of the Pomeron exchange near threshold.
