Abstract
Photoproduction of on the nucleon is investigated within the Regge framework, and the reaction mechanism is analyzed based on the data existing in the channels and . The Reggeization of the -channel meson exchanges is employed to construct the photoproduction amplitude. The Rarita-Schwinger formalism is applied for the spin- strangeness-baryon with a special gauge prescription utilized for the convergence of these reaction processes. Within a set of coupling constants determined from the symmetry argument for and and from the duality and vector dominance for , the data of both processes are reproduced to a good degree. The production mechanism of these processes is featured by the dominance of the contact term over the exchange. The role of is found to be more important than that of .
