4He(e,e) cross section data at 328, 365 and 725 MeV have been analyzed using the quasi-free scattering (QFS) model of Lightbody and O'Connell. The QFS model provides an improved description of the shape and magnitude of the cross section data when compared with plane-wave impulse approximation calculations, particularly at higher values of the electron energy loss. Although the nucleon separation energy is about 20 MeV in 4He, the best QFS results are obtained for a 6 MeV value.
