    "abstract": "The spectral function of 4He is calculated with the Lorentz integral\ntransform method in a large energy and momentum range. The excitation spectrum\nof the residual 3N-system is fully taken into account. The obtained spectral\nfunction is used to calculate the quasi elastic longitudinal (e,e\u0027) response\nR_l of 4He for q=300, 400, and 500 MeV/c. Comparison with the exact R_l shows a\nrather sizeable disagreement except in the quasi elastic peak, where the\ndifferences reduce to about 10% at q=500 MeV/c. It is shown as well that very\nsimple momentum distribution approximations for the spectral function provide\npractically the same results for R_l as the exact spectral function.",
