Description
The characteristics of the Jefferson Lab electron beam, together with those of the experimental equipment, offer a unique opportunity to study hypernuclear spectroscopy via electromagnetic induced (e,e′K+) reactions. Experiment 94-107 started a systematic study on 1p-shell targets, 12C, 9Be and 16O. For 12C for the first time measurable strength in the core-excited part of the spectrum between the ground state and the p state was shown in the 12ΛB spectrum. For 16O a high-quality 16ΛN spectrum was produced for the first time with sub-MeV energy resolution. A very precise Λ binding energy value for 16ΛN, calibrated against the elementary (e,e′K+) reaction on hydrogen, has also been obtained. Preliminary data on the 9ΛLi spectrum shows some disagreement in strength for the second and third doublet with respect to the theory
