  "abstract": "Inspired by the preliminary experimental data by the CLAS Collaboration, the $K^{\\ast 0}\\Lambda$ 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 $K$-exchange $t$ channel plays a dominant role for the $K^{\\ast 0}\\Lambda$ photoproduction. The contribution from the $\\kappa$ exchange is found one order of magnitude smaller than that from $K$ 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 $K^{\\ast 0}\\Lambda$ photoproduction.",
