Differential cross sections at t=tmin and decay asymmetries for the γp→ϕp reaction have been measured using linearly polarized photons in the range 1.5 to 2.9 GeV. These cross sections were used to determine the Pomeron strength factor. The cross sections and decay asymmetries are consistently described by the t-channel Pomeron …
