Abstract
The differential cross section has been measured for the reaction γ+p→K + + Λ atk=1.3 GeV andCM angles between 6 ° and 90 ° and for the reaction γ+p→K + + ∑0 atk=1.45 GeV andCM angles between 10 ° and 85 °. In addition 10 differential cross sections of the two reactions in the energy region betweenk=1.327 and 1.416 GeV and angles between θ cm =11.2 ° and 62 ° have been obtained. The results are compared with Regge-cut-model fits by Meyer zu Hörste and Pfeil1 taking into account all availableK + photoproduction data.
