Abstract: (Elsevier)

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, C12, Be9 and O16. For C12 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 B@L12 spectrum. For O16 a high-quality N@L16 spectrum was produced for the first time with sub-MeV energy resolution. A very precise @L binding energy value for N@L16, calibrated against the elementary (e,e^'K^+) reaction on hydrogen, has also been obtained. Preliminary data on the Li@L9 spectrum shows some disagreement in strength for the second and third doublet with respect to the theory.
