英文摘要	The nonleptonic weak decay of Lambda(+)(c) -> (K) over bar (0)eta p is analyzed from the viewpoint of probing the N(1535) resonance, which has a big decay branching ratio to eta N. Up to an arbitrary normalization, the invariant mass distribution of eta p is calculated with both the chiral unitary approach and an effective Lagrangian model. Within the chiral unitary approach, the N(1535) resonance is dynamically generated from the final-state interaction of mesons and baryons in the strangeness zero sector. For the effective Lagrangian model, we take a Breit-Wigner formula to describe the distribution of the N(1535) resonance. It is found that the behavior of the N(1535) resonance in the Lambda(+)(c) -> (K) over bar N-0(1535) -> (K) over bar (0)eta p decay within the two approaches is different. The proposed Lambda(+)(c) decay mechanism can provide valuable information on the properties of the N (1535) and can in principle be tested by facilities such as BEPC II and SuperKEKB.
