Elastic Scattering of Neutrons from Carbon and Oxygen in the Energy Range 3.0 to 4.7 MeV

Transfer reactions as tool for nuclear astrophysics: the 13C(a,n)16O case

“…We find Γ α = 0.09 keV, and Γ n = 400 keV. These results are slightly different from the recommended values [18] (Γ α = 0.07 keV, Γ n = 280 keV), but are consistent with a 16 O+n measurement of Lister et al [19]. Note, that in Ref.…”

Resonance parameter and covariance evaluation for16O up to 6 MeV

“…As an example, Figure 3 shows a comparison of SAMMY fits with the total cross section of Danon et al [18] measured at the RPI linear accelerator [28] (bottom curve) and the total cross section of Cierjacks et al [20]. In Figure 4, a comparison of the differential elastic scattering data of Lister and Sayers [29] for energies in the range 3-4 MeV are shown. A good representation of the experimental data with the RPs is obtained.…”

“…Among the data used in the silicone evaluation there were data from measurements of enriched silicon samples for 28 Si, 29 Si, and 30 Si in the form of silicon dioxide, that is, 28 SiO 2 , 29 SiO 2 , and 30 SiO 2 . Consequently, there existed the need for RP for oxygen to complete the RP evaluation for silicon.…”

Ab initio optical potentials and nucleon scattering on medium mass nuclei

“…Most of the virtual excitations responsible for this, especially at low energy, are accessed by coupling to hundreds of 2p1h configurations for 17 O and appear as clear spikes or "smoothed" oscillations in the figure. The SCGF-ADC(3) approach NNLOsat and compared to the empirical data from [44,46]. has the advantage of including these states naturally, even to large energies, so it describes efficiently the relevant physics.…”
