| Abstract: | Photoproduction of Φ-vector-mesons has been studied from reaction threshold up to W = 2.4 GeV with the SAPHIR spectrometer at the Bonn electron stretcher ring ELSA. Total cross-sections, differential cross-sections and decay angular distributions were measured. We find evidence for strong non-diffractive contributions to Φ photoproduction.
