英文摘要	By assuming that the Lambda(c)(2940) is a pD(0) molecular state with spin-parity J(P) = 1/2(+) and J(P) = 1/2(-), the photoproduction of charmed Lambda(c)(2940) baryon in the gamma n -> D-Lambda(c)(2940)(+) process is investigated with an effective Lagrangian approach. It is found that the contributions from the t-channel with D* exchange are dominant, while those from the s-channel with nucleon pole exchange give a sizeable contribution around the threshold. The contributions from the u-channel and contact term are very small. The total cross section of the gamma n -> D-Lambda(c)(2940)(+) reaction is estimated, which indicate it is feasible to searching for the charmed Lambda(c)(2940) baryon at the COMPASS experiment.
