摘要：

Differential cross sections and decay asymmetries for coherent phi-meson photoproduction from deuterons were measured for the first time at forward angles using linearly polarized photons at E-gamma = 1.5-2.4 GeV. This reaction offers a unique way to directly access natural-parity pomeron dynamics and gluon exchange at low energies. The cross sections at zero degrees increase with increasing photon energy. The decay asymmetries demonstrate a complete dominance of natural-parity exchange processes, showing that isovector unnatural -parity pi-meson exchange is small. Nevertheless the deduced cross sections of phi-mesons from nucleons contributed by isoscalar t-channel exchange processes are not well described by the conventional pomeron model.
