Abstract
An experimental study of the 16O(e,e′K+)Λ16N [superscript 16 O (e, e prime K superscript +) superscript 16 subscript lambda N] reaction has been performed at Jefferson Lab. A thin film of falling water was used as a target. This permitted a simultaneous measurement of the p(e,e′K+)Λ,Σ0 [p (e, e prime K superscript +) lambda, sigma superscript 0] exclusive reactions and a precise calibration of the energy scale. A ground-state binding energy of 13.76±0.16 MeV was obtained for Λ16N [superscript 16 subscript lambda N] with better precision than previous measurements on the mirror hypernucleus Λ16O [superscript 16 subscript lambda O]. Precise energies have been determined for peaks arising from a Λ [lambda]in s and p orbits coupled to the p1/2 [p subscript 1/2] and p3/2 [p subscript 3/2] hole states of the 15N [superscript 15 N] core nucleus
