N2 - We report the first measurements of absolute branching fractions for the W-exchange-only processes Λc +→Ξ0K+ and Λc +→Ξ(1530)0K+ with the double-tag technique, by analyzing an e+e− collision data sample, that corresponds to an integrated luminosity of 567 pb−1 collected at a center-of-mass energy of 4.6 GeV by the BESIII detector. The branching fractions are measured to be B(Λc +→Ξ0K+)=(5.90±0.86±0.39)×10−3 and B(Λc +→Ξ(1530)0K+)=(5.02±0.99±0.31)×10−3, where the first uncertainties are statistical and the second systematic. Our results are more precise than the previous relative measurements.
