title = "Spectroscopy of the neutron-rich hypernucleus He Λ7 from electron scattering",
abstract = "The missing mass spectroscopy of the HeΛ7 hypernucleus was performed using the Li7(e,e′K+)HeΛ7 reaction at the Thomas Jefferson National Accelerator Facility Hall C. The Λ-binding energy of the ground-state (1/2+) was determined with a smaller error than that of the previous measurement, being BΛ=5.55±0.10stat.±0.11sys.MeV. The experiment also provided new insight into charge symmetry breaking in p-shell hypernuclear systems. Finally, a peak at BΛ=3.65±0.20stat.±0.11sys.MeV was observed and assigned as a mixture of 3/2+ and 5/2+ states, confirming the {"}gluelike{"} behavior of Λ, which makes an unstable state in He6 stable against neutron emission.",
