“…4 and 5, respectively, together with the measured data. [37][38][39][40][41] The present results agree with measured total cross sections almost perfectly up to 200 MeV. It should be noted that the calculated values of the spherical model are apparently larger than our results and the measured data for neutron total cross sections below 10 MeV, while both calculations result in almost the same values for proton total-reaction cross sections.…”

Neutron nuclear data on 28;29;30 Si have been calculated for the evaluated nuclear data library JENDL-4. Simultaneously calculated are the total, elastic and inelastic scattering, and ðn; pÞ, ðn; Þ, ðn; Þ, ðn; 2nÞ, ðn; 3nÞ, ðn; npÞ, and ðn; nÞ reaction cross sections, the angular distributions of emitted neutrons, and the energy distributions of emitted particles and -rays. The statistical model was applied to calculate these quantities. Coupled-channel optical model parameters were obtained so as to reproduce measured cross sections. Preequilibrium and direct-reaction processes were taken into account in addition to the compound process. It is confirmed that the present calculations are almost consistent with available experimental data. The calculated data are compiled into JENDL-4.

“…Although experimental data exist to much lower energies, any effective mean field prescription for the optical potential at such low energies is not appropriate. However, in a recent paper [52], a multi-channel algebraic scattering (MCAS) theory has been developed with which the low [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43] 16 O [44], [40], [45] 40 Ca [34], [46], [38], [47], [45], [43] 90 Zr [48], [38], [49], [39] 208 Pb [30], [32], [33], [35], [46], [50], [38], [39], [40], [51], [45], [43] -0 energy range should be covered. This MCAS approach lends itself to specification of the dynamic polarization potential resulting from a summation over all diverse channel functions allowed in that theory.…”

Comparison of optical model results from a microscopic Schrödinger approach to nucleon-nucleus elastic scattering with those from a global Dirac phenomenology

Comparisons are made between results of calculations for intermediate energy nucleon-nucleus scattering for 12 C, 16 O, 40 Ca, 90 Zr, and 208 Pb, using optical potentials obtained from global Dirac phenomenology and from a microscopic Schrödinger model. Differential cross sections and spin observables for scattering from the set of five nuclei at 65 MeV and 200 MeV have been studied to assess the relative merits of each approach. Total reaction cross sections from proton-nucleus and total cross sections from neutron-nucleus scattering have been evaluated and compared with data for those five targets in the energy range 20 MeV to 800 MeV. The methods of analyses give results that compare well with experimental data in those energy regimes for which the procedures are suited.

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.
