英文摘要	We report the first direct measurement of decays of the lambda(+)(c) baryon involving the neutron. the analysis is performed using 567 pb(-1) of e(+)e(-) collision data collected at root s = 4.599 gev with the besiii detector at the bepcii collider. we observe the decay lambda(+)(c) -> nk(s)(0)pi(+) and measure the absolute branching fraction to be b(lambda(+)(c) -> nk(s)(0)pi(+)) = [1.82 +/- 0.23(stat) +/- 0.11(syst)]%. a comparison to b[lambda(+)(c) -> p( (k) over bar pi)(0)] provides an important test of isospin symmetry and final state interactions.
