Abstract:
The phenomenological and semi-microscopic values of the potentials found in the angular distribution of
scattering of ions 6
Li - lithium,
16О - oxygen from the target nucleus 12C- carbon accelerated at low energies are
determined. The experimental data of elastic scattering were analyzed based on the optical model and the double
folding model. Based on the folding model, the density-dependent new Fetal potential of Yukawa 3 terms of
effective nucleon-nucleon interactions was first used. The density-dependent Fetal, Paris, Reid microfolding
potentials were constructed in the double folding model as a real part of the optical potential. The efficacy of the
new Fetal micropotential at laboratory energies of 28 MeV and 30 Mev for the 16О+12С nuclear system was
studied in comparison with the Reid, Paris variants. The efficacy of the new Fetal potential at laboratory energies
of 12.3 MeV and 20 MeV for the 6
Li+12C system has been studied in comparison with Reid and Paris potentials.
The relative errors of phenomenological theoretical analysis and experimental cross-sections were determined in
the range of 1.1 -3.0. As a result of semimicroscopic analysis, the coefficients of renormalization of folding
potentials in the range Nr=0.8-1.0 were determined. The data obtained will be used in various fundamental
research, in particular in future thermonuclear installations and nuclear astrophysics.
