英文摘要	We use an effective lagrangian approach in the tree-level approximation to analyze the high-precision cross-section data for reported by the clas collaboration. apart from the t-channel k, , exchanges, the s-channel nucleon (n) exchange, the u-channel , , exchanges, and the generalized contact current, we found that at least two nucleon resonances ('s) should be considered to well describe the high-precision cross-section data. one is the that is responsible for the shape of the angular distribution near the threshold via its interference with the t-channel k exchange, and the other could be one of the , , , and . the results for , t and p are predicated and it is pointed out that more data on these observables are needed to further pin down the resonance contents and their associated parameters in this reaction.
