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.
