High Resolution Spectroscopy of 16NLambda by Electroproduction
Abstract
An experimental study of the 16O(e,e'K+)16NLambda 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+)Lambda,Sigma0 exclusive reactions and a precise calibration of the energy scale. A ground-state binding energy of 13.76 +/- 0.16 MeV was obtained for 16NLambda with better precision than previous measurements on the mirror hypernucleus 16OLambda. Precise energies have been determined for peaks arising from a Lambda in s and p orbits coupled to the p1/2 and p3/2 hole states of the 15N core nucleus.
