Abstract

Eta-prime meson photoproduction on the nucleon has been studied with effective lagrangian approach using isobar model. Effective lagrangian will be used to calculate invariant amplitude for s-channel and u-channel Born term, t-channel vector-meson exchange term, and resonance spin 1/2, spin 3/2, spin 5/2, and spin 7/2. Invariant amplitude calculated by using analitic and numeric method which then will be obtained differential cross section. The result of differential cross section will be compared with experimental data. This work will also predict polarization observable.
