Final state interactions in 4He (e, e 'p) 3H at large proton energy

At large proton energy, the final state interactions of the knocked out nucleon in ( e, e^'p) reactions off nuclear targets can be described within the eikonal approximation, treating the spectator particles as a collection of fixed scattering centers. We use a generalization of this approach, suitable to take into account the possible occurrence of color transparency, to carry out an accurate calculation of the missing momentum distribution of the process ⁴He( e, e^'p) ³H. The pattern of final state interactions effects is analyzed for different kinematical setups in the domain corresponding to 2≤ Q²≤20 (GeV/ c) ².
