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 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 Λ12B spectrum. A high-quality Λ16N spectrum was produced for the first time with sub-MeV energy resolution. A very precise Λ binding energy value for Λ16N, calibrated against the elementary (e,e′K+) reaction on hydrogen, has also been obtained. Λ9Li spectrum shows some disagreement in strength for the second and third doublet with respect to the theory.
