Λ9Li and Λ16N high resolution spectroscopy by electron scattering at Jefferson Lab in Hall A

The preliminary results of the Λ 9 Li and Λ 16 N spectra obtained by electron scattering experiment in Hall A at Jefferson Lab in the framework of the experiment E94-107 are reported. These hypernuclei are produced bombarding respectively a 9Be and a waterfall target. After a short description of the experimental equipment and of the data analysis procedures, the main characteristics of the measured spectra, as excited levels, energy resolution, and signal to noise ratio are evidenced.
