Query: Theoretical predictions for extraction of GEn from semi-inclusive
  electron scattering on polarized 3He based on various nucleon-nucleon
  interactions   The process 3He(e,e'n) with polarized electrons and 3He in the initial state
is theoretically analyzed with the aim to search for sensitivity to the
electric form factor of the neutron, GEn. Faddeev calculations based on five
high precision nucleon-nucleon force models are employed and stability versus
exchange of the nucleon-nucleon forces is demonstrated.
