A comprehensive phenomenological, semi-microscopic, and CRC analysis of 15N elastic scattering from 13C and 19F nuclei

Abstract

In the present study, the angular distributions obtained at beam energies Elab = 30.0, 32.0 and 45.0 MeV for the 15N+ 13С reaction and Elab = 23.0, 26.0 and 29.0 MeV for the 15N+ 19F system were subjected to a comprehensive reanalysis using the optical model, the double folding model, and the coupled reaction channel (CRC) method. The main objective of the study was to establish the optimal optical potential through phenomenological and semi-microscopic analysis. Through careful calculations, the acceptable parameters of the potentials and their energy dependencies were derived for both nuclear systems. Notably, the angular distributions were well reproduced, indicating the effectiveness of the theoretical models used. In back angle scattering analysis, the CRC has very good agreement with the experimental values. As a result of the analysis, spectroscopic amplitudes were extracted for the 15N → 13C + d and 19F → 15N + α configurations at different energies of the incident 15N ions. The obtained results of spectroscopic amplitudes were subsequently compared with previously reported values, facilitating an assessment of the consistency and accuracy of the present work.
