Abstract
In the present work R-Matrix calculations regarding the differential cross sections of the natMg(p,p0)natMg elastic scattering for Ep,lab = 0.70 – 4.25 MeV were implemented using the Azure2 code [1]. A coherent set of differential cross sections, the first to cover the Ep,lab = 2.45 – 4.25 MeV energy range [2], measured at the Tandem Accelerator laboratory of NCSR “Demokritos” was used as a basis for the calculations. These results were able to accurately reproduce both the experimental dataset as well as the current evaluation [3] which covers the Ep,lab = 0.7 to 2.7 MeV energy range.
