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.

“…The absolute normalization of the data has been obtained from knowledge of the total elastic cross section, which has been determined from the difference between the total cross section (σ T ) [13] and the reaction cross section (σ R ) [14,15]. This σ T -σ R method, which is expected to have an uncertainty of about 3 %, has been used to normalize the 12 C data.…”

Elastic neutron scattering from 12 C, 14 N, 16 O, 28 Si, 40 Ca, 56 Fe, 89 Y and 208 Pb has been studied at 96 MeV in the 10 − 70 degree interval, using the SCANDAL (SCAttered Nucleon Detection AssembLy) facility. The results for 12 C and 208 Pb have recently been published, while the data on the other nuclei are under analysis. The achieved energy resolution, 3.7 MeV, is about an order of magnitude better than for any previous experiment above 65 MeV incident energy. A novel method for normalization of the absolute scale of the cross section has been used. The estimated normalization uncertainty, 3 %, is unprecedented for a neutron-induced differential cross section measurement on a nuclear target. Elastic neutron scattering is of utmost importance for a vast number of applications. Besides its fundamental importance as a laboratory for tests of isospin dependence in the nucleon-nucleon, and nucleon-nucleus, interaction, knowledge of the optical potentials derived from elastic scattering come into play in virtually every application where a detailed understanding of nuclear processes are important. Applications for these measurements are nuclear waste incineration, single event upsets in electronics and fast neutron therapy. The results at light nuclei of medical relevance ( 12 C, 14 N and 16 O,) are presented separately. In the present contribution, results on the heavier nuclei are presented, among which several are of profound relevance to accelerator-driven systems for transmutation.
