Abstract :
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 image reactions. Experiment 94-107 started a systematic study on 1p-shell targets, image, image and image. For image 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 image spectrum. For image a high-quality image spectrum was produced for the first time with sub-MeV energy resolution. A very precise Λ binding energy value for image, calibrated against the elementary image reaction on hydrogen, has also been obtained. Preliminary data on the image spectrum shows some disagreement in strength for the second and third doublet with respect to the theory.
