[en] The hypernuclear spectroscopy program planned for Hall A of Thomas Jefferson National Accelerator Facility as well as the two fundamental changes to the Hall A experimental apparatus needed for this program are described. The program involves a precise study of various light hypernuclei ⁷Li_Λ, ⁸Be_Λ, ¹²C_Λ and ¹⁶O_Λ. The two changes consist of the addition of two septum magnets to the Hall A spectrometers, allowing measurements at angles as far forward as 6φ, and the installation of a Ring Imaging Cerenkov detector (RICH) in the detector package, greatly enhancing the particle identification capability

[en] We report the first measurement using a solid polarized target of the neutron electric form factor Gⁿ_E via d-vector(e-vector, e'n)p. Gⁿ_E was determined from the beam-target asymmetry in the scattering of longitudinally polarized electrons from polarized deuterated ammonia (¹⁵ND₃). The measurement was performed in Hall C at Thomas Jefferson National Accelerator Facility in quasifree kinematics with the target polarization perpendicular to the momentum transfer. The electrons were detected in a magnetic spectrometer in coincidence with neutrons in a large solid angle segmented detector. We find Gⁿ_E = 0.04632±0.00616(stat)±0.00341(syst) at Q² = 0.495 (GeV/c)²
