Astrophysical S-Factor Analysis for $^{14}$N(p,γ)$^{15}$O Radiative Capture Reaction Based on p + $^{14}$N Elastic Scattering at Low Energies

Аннотация

Indirect experimental angular distributions data for protons elastically scattered from ¹⁴N target nuclei at low energies: 1.8, 2.2, 3.0, 3.3, and 3.8 MeV are extracted from the available experimental excitation functions for p + ¹⁴N. These extracted data are subjected to theoretical analysis within the framework of single folding optical potential (SFOP) model in order to obtain the optimal potential that could fairly reproduce the p + ¹⁴N elastic scattering angular distributions. The obtained potential parameters are then used to calculate the astrophysical S-factor for ¹⁴N(p,γ)¹⁵O radiative capture reaction at very low energies where no experimental data is available and compared with the available experimental data.
