Abstract: (Elsevier)

The momentum distributions for the knock-out of 2p protons from 90 Zr leading to the 1 2 − ground state and the 3 2 − excited state at 1.507 MeV in 89 Y have been determined at two outgoing proton energies (70 and 100 MeV) in a high-resolution (e,e′p) experiment. Using elastic proton-nucleus scattering data as a constraint, a proper description of the (e,e′p) data is obtained if the optical potential used to calculate the final state interaction is more absorptive inside the nucleus at 100 MeV than at 70 MeV. The deduced strength and orbit radii are compared to theory and to the result of a (d, 3 He) experiment.
