“…Fig. 5 compares the calculated differential elastic scattering cross sections for the p+ 58 Ni system in the 20-60 MeV range with the experimental data from ( Van Hall et al, 1977;Fricke et al, 1967;Fulmer et al, 1969;Sakaguchi et al, 1982) and with the data predicted by CH89. A good agreement has been attained at low and intermediate energies.…”

The nucleon differential elastic scattering cross sections, the total proton reaction cross sections, and the single-particle energies of nucleon bound states for 40 Ca, 90 Zr, and 208 Pb nuclei are reanalyzed in terms of the dispersive optical model at energies ranging from -75 MeV to 60 MeV. The resultant real effective Woods-Saxon potential, which corresponds to the dispersive potential, is studied as dependent on A, Z, and E and on projectile specie (proton or neutron). For the first time, a parameterization of the Woods-Saxon real part of the nucleonnucleus optical potential is proposed for the 208 40 A nuclei at energy ranging from -60 MeV to +60 MeV, including a range near the Fermi energy. The parameterization reflects the dispersion relation between the real and imaginary parts of the optical model potential through the energy dependence of the radius parameter of the real part of the potential. The method to determine the imaginary part of the optical model potential, which is symmetrical relative to the Fermi energy, is also proposed for the 208 40 A nuclei. The differential elastic scattering cross sections, the total neutron interaction cross sections, the total proton reaction cross sections, and the single-particle energies of the nucleon bound states calculated in terms of the proposed nucleon-nucleus potential parameterization for some of the n,p+A ( 40 A) systems are compared with the available experimental data, yielding a fairly good agreement.

“…Also, the prediction for 4 + (4.62 MeV) at 21.7 MeV underestimates slightly the experimental data at forward angles. Figure 8 shows the calculated proton elastic scattering angular distributions compared with the experimental data 17,[31][32][33][34][35] for nine incident energies from 26.2 to 180 MeV for 28 Si. The calculation reproduces the experimental data fairly well at incident energies below 100 MeV, while underestimation is seen at the first and second minima of the angular distributions for energies above 100 MeV.…”

A consistent analysis for nuclear level structure and nucleon scattering data up to 200 MeV was performed for sd-shell nuclei, 28,30 Si, using a unified framework of soft-rotator model and coupled-channels approach. The 28,30 Si were assumed to be deformed nuclei having oblate shapes. The soft-rotator model parameters were determined so as to reproduce measured collective levels of 28,30 Si up to an excitation energy of around 10 MeV. The relativistic kinematics and global optical potential form were taken into account in the coupled-channels optical model analysis, and the optical model parameters were derived. The calculation showed good agreement with experimental data for both collective levels and nucleon interaction data-neutron total cross sections, proton reaction cross sections, and nucleon scattering angular distributions.
