The analysis is performed using 567  pb−1 of e+e− collision data collected at √s=4.599  GeV with the BESIII detector at the BEPCII collider. We observe the decay Λ+c→nK0Sπ+ and measure the absolute branching fraction to be B(Λ+c→nK0Sπ+)=[1.82±0.23(stat)±0.11(syst)]%. A comparison to B[Λ+c→p(¯Kπ)0] provides an important test of isospin symmetry and final state interactions UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000616086 ER -
