The ratio of the transverse to longitudinal (e, e′p) strength in the quasi-elastic peak is investigated within a non-relativistic Hartree-Fock (HF) and continuum random-phase approximation (RPA) reaction model. Calculations are performed for proton knockout from different orbitals in 12C and 40Ca. Each single-particle state is found to show a particular behaviour in the transverse to longitudinal ratio. Comparison with experimental data indicates that a beneficial role can be attributed to the RPA correlations.
