N2 - Based on 4.5 fb-1 of e+e- collision data accumulated at center-of-mass energies between 4599.53 and 4698.82 MeV with the BESIII detector, we measure the absolute branching fraction of the Cabibbo-favored decay Λc+→nKS0π+ with the precision improved by a factor of 2.8 and report the first evidence for the singly-Cabibbo-suppressed decay Λc+→nKS0K+. The branching fractions for Λc+→nKS0π+ and Λc+→nKS0K+ are determined to be (1.86±0.08±0.04)×10-2 and (3.9-1.4+1.7±0.3)×10-4, respectively, where the first uncertainties are statistical and the second ones are systematic.
