英文摘要	Inspired by the preliminary experimental data by the CLAS Collaboration, the K(0) Lambda photoproduction off a neutron is studied within an effective Lagrangian approach. The contributions from the Born terms including s, u, and t channels are considered to calculate the amplitude, with which the cross sections are calculated and compared with preliminary CLAS data. The theoretical results indicate that the contribution from the t-channel K exchange plays a dominant role for the K(0) Lambda photoproduction. The contribution from the. exchange is found one order of magnitude smaller than that from the K exchange. Both the Regge model and the Feynman model are applied to treat the t-channel contribution. The discrepancy between two models is found small in the energy range of CLAS data and predicted to become obvious at energies higher than 3 GeV. More precise experimental data especially at backward angles will be helpful to further understand the interaction mechanism of the K*(0) Lambda photoproduction.
