“…The experimental setup is almost the same as that described in detail by El-Kadi et al [26] and so only a brief description is given here. Unpolarized deuteron beams of energies 14.4 and 9.39 MeV were extracted from the FN tandem Van de Graaff accelerator.…”

Neutron elastic-scattering angular distributions were measured at beam energies of 11.9 and 16.9 MeV on 40,48 Ca targets. These data plus other elastic-scattering measurements, total and reaction cross sections measurements, (e, e ′ p) data, and single-particle energies for magic and doubly magic nuclei have been analyzed in the dispersive optical model (DOM) generating nucleon self-energies (optical-model potentials) which can be related, via the many-body Dyson equation, to spectroscopioc factors and occupation probabilities. It is found that for stable nuclei with N ≥ Z, the imaginary surface potential for protons exhibits a strong dependence on the neutron-proton asymmetry. This result leads to a more modest dependence of the spectroscopic factors on asymmetry. The measured data and the DOM analysis of all considered nuclei clearly demonstrates that the neutron imaginary surface potential displays very little dependence on the neutron-proton asymmetry for nuclei near stability (N ≥ Z).

“…These new experimental elastic scattering cross sections are compared with existing data from the literature [4,5,[7][8][9]12] and evaluated data from ENDF/B-VII.1 [18], JEFF-3.1 [29], and JENDL-4.0 [30] compilations; these comparisons are shown in Fig. 3.…”

“…3. Previously reported data [4][5][6][7][8][9][10][11][12] were retrieved from the experimental nuclear reaction data (EXFOR) database [31]. Reasonable agreement is observed among the evaluations and the experimental data for E n > 3.5 MeV, while more variation is observed for E n ≤ 3.5 MeV.…”

“…In the fast-neutron energy region, the total cross sections for neutron-induced reactions on 56 Fe are dominated by elastic and inelastic scattering processes. A number of studies of fast-neutron scattering from 56 Fe have been reported [4][5][6][7][8][9][10][11][12]. Despite these efforts, there are still significant discrepancies among predictions from existing evaluated data libraries, particularly for the inelastic scattering processes [13].…”
