“…Although the PH optical potential provides good fits to proton elastic scattering data [67,82], we find that its predictions for integrated cross sections are substantially larger than the data. Similarly, PH calculations for proton inelastic scattering to states with surfacepeaked transition densities also tend to produce cross sections that are too large [1,77,5]. We have argued [2] that for finite nuclei nonlocal corrections to the LDA suppress the interaction strength in the surface region, producing smaller inelastic cross sections for surface-peaked states and smaller integrated cross sections.…”

“…The effect of these differences upon elastic and inelastic scattering calculations has been surveyed in a series of papers by Kelly and collaborators in which transition densities measured by electroexcitation are used to minimize uncertainties due to nuclear structure and to isolate the effective interaction for detailed examination [1][2][3][4][5][6]. Transition densities which are strong in the interior provide information about the high-density properties of the effective interaction, whereas surface-peaked transition densities reveal the low-density properties.…”

“…Thus, various phase-equivalent optical potentials can produce significantly different predictions when employed to analyze other reactions. Alternatively, we have developed an empirical effective interaction (EEI) [1][2][3][4][5][6] based upon the density dependence predicted by nuclear matter theories of the effective interaction, but where the parameters are fitted to inelastic scattering data. Transition densities fitted to electroexcitation data are used to minimize uncertainties due to nuclear structure.…”

Nuclear transparency in the (e, e ′ p) reaction for 135 ≤ T p ≤ 800 MeV is investigated using the distorted wave approximation. Calculations using densitydependent effective interactions, both empirical and theoretical, are compared with phenomenological optical potentials. We find that nuclear transparency is well correlated with proton absorption and neutron total cross sections and that calculations using density-dependent effective interactions provide the best agreement with data. Nuclear transparency calculations are compared with recent electron scattering data for Q 2 < 2 (GeV/c) 2 . For T p < ∼ 200 MeV we find that there is considerable sensitivity to the choice of optical model and that the empirical effective interaction provides the best agreement with the data, but remains 5-10% low. For T p > ∼ 300 MeV we find that there is much less difference between these models, but that the calculations significantly underpredict transparency data and that the discrepancy increases with A. The differences between Glauber and optical model calculations are related to their respective definitions of the semi-inclusive cross section. By using a more inclusive summation over final states the Glauber model emphasizes nucleonnucleon inelasticity, whereas with a more restrictive summation the optical model emphasizes nucleon-nucleus inelasticity; experimental definitions of the semi-inclusive cross section lie between these extremes.

We derive and calculate the multiple scattering expansion of the Kerman-McManus-Thaler optical potential to second order in the free nucleon-nucleon transition amplitude and clarify the physical content of the interaction. Calculations are presented for the elastic scattering of protons from ' 0 at 135, 200, and 300 MeV incident energies, paying particular attention to the nonlocalities inherent in the second-order potential. It is shown that these effects result in a significant reduction in the proton-target absorption.PACS number 24.10.Ht, 24.70.+s, 25.40.Cm
