“…The results of calculations made using SHF wave functions are depicted by the solid curves, while those found from using WS wave functions are shown by the dashed curves. SHF predictions of the elastic cross sections made with the g-folding model agree very well with the data [20,26,30,31] except for the overly sharp defined minima they give with the lower energies. For the two larger energies, these SHF results give better fits to the data than do those found using the WS functions, noticeably at large scattering angles.…”

Differential cross sections and analyzing powers for elastic scattering from, and for inelastic proton scattering to a set of 2 + 1 states in, 12 C, 20 Ne, 24 Mg, 28 Si and 40 Ca, and for a set of energies between 35 to 250 MeV, have been analyzed. A g-folding model has been used to determine optical potentials and a microscopic distorted wave approximation taken to analyze the inelastic data. The effective nucleon-nucleon interactions used to specify the optical potentials have also been used as the transition operators in the inelastic scattering processes. Shell and large space Hartree-Fock models of structure have been used to describe the nuclear states.

“…When summing up their feeding of the 1.369 MeV level, it amounts to approximately 50% of the 1.369 MeV cross section above E p = 10 MeV. The direct population of the 1.369 MeV level by inelastic scattering can be inferred from the differential cross-section data of Crawley and Garvey [31] and Hassell et al [32]. It amounts to ≈140 mb at E p = 17 MeV, ≈100 mb at E p = 20 MeV, and ≈90 mb at E p = 25 MeV.…”

γ -ray production cross sections for proton and α-particle interactions with 12 C, 16 O, 24 Mg, and Fe have been measured in the energy range 5-25 MeV with proton beams and 5-40 MeV with α-particle beams. Isotopically pure foils of 24 Mg and foils of natural isotopical composition of C, MgO, and Fe have been used. γ -ray angular distributions were obtained with five high-purity Ge detectors with bismuth germanate Compton shields placed at angles of 45 • to 157.5 • . Cross sections for more than 50 different γ -ray transitions were extracted, and for many of them no data have been published before. Comparison of present data with data available in the literature shows mostly good to excellent agreement. In addition to the production cross sections, high-statistics, low-background line shapes of the 4.438 MeV 12 C γ ray from inelastic scattering off 12 C and spallation of 16 O were obtained. Comparison with nuclear reaction calculations shows that these data place interesting constraints on nuclear reaction models.

“…The validity of our OMP for each isotopic chain ranges from E p = 0 − 250 MeV for 24 Mg, E p = 0 − 200 MeV for 28 Si and E p = 0 − 160 MeV for 56 Fe. The proton and neutron experimental angular distribution cross sectiondata can be found in Refs [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76] for 24,25,26 Mg, Refs.

Gamma-ray production cross section excitation functions have been measured for 30, 42, 54 and 66 MeV proton beams accelerated onto targets of astrophysical interest, nat C, C + O (Mylar), nat Mg, nat Si and 56 Fe, at the Sector Separated Cyclotron (SSC) of iThemba LABS (near Cape Town, South Africa). The AFRODITE array equipped with 8 Compton suppressed HPGe clover detectors was used to record γ-ray data. For known, intense γ-ray lines the previously reported experimental data measured up to Ep ≃ 25 MeV at the Washington and Orsay tandem accelerators were extended to higher proton energies. Our experimental data for the last 3 targets are reported here and discussed with respect to previous data and the Murphy et al. compilation [ApJS 183, 142 (2009)], as well as to predictions of the nuclear reaction code TALYS. The overall agreement between theory and experiment obtained in first-approach calculations using default input parameters of TALYS has been appreciably improved by using modified optical model potential (OMP), deformation, and level density parameters. The OMP parameters have been extracted from theoretical fits to available experimental elastic/inelastic nucleon scattering angular distribution data by means of the coupled-channels reaction code OPTMAN. Experimental data for several new γ-ray lines are also reported and discussed. The astrophysical implications of our results are emphasised.
