摘要：

We investigate the gamma p -> phi K+ Lambda reaction near threshold within an effective Lagrangian approach and the isobar model. Various nucleon resonances caused by the pi and eta meson exchanges and background contributions are considered. It is shown that the contribution from the N*( 1535) resonance caused by the eta meson exchange plays the predominant role. Hence, this reaction provides a good new platform to study the N*( 1535) resonance. The predicted total cross section and specific features of the angular distributions can be tested by future experiments.
