Использование нового потенциала B3Y-Fetal при полумикроскопическом анализе рассеяния ускоренных ядер 6Li - лития и 16O - кислорода от ядра 12C – углерода

Abstract

The phenomenological and semi-microscopic values of the potentials found in the angular distribution of scattering of ions ⁶Li - 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 ⁶Li+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.
