Sažetak
The binding energy of 7He-Lambda has been obtained for the first time with reaction spectroscopy using the (e, e'K+) reaction at Jefferson Lab's Hall C. A comparison among the binding energies of the A=7 T=l iso-triplet hypernuclei, 7He-Lambda, 7Li*-Lambda and 7Be-Lambda, is made and possible charge symmetry breaking (CSB) in the Lambda-Nucleon potential is discussed. For 7He-Lambda and 7Be-Lamnda, the shifts in binding energies are opposite to those predicted by a recent cluster model calculation, which assumes that the unexplained part of the binding energy difference between 4H-Lambda and 4He-Lambda, is due to the CSB of the Lambda-Nucleon potential. Further examination of CSB in light hypernuclear systems is required both experimentally and theoretically.
