New measurement and analysis for the <sup>15</sup>N + <sup>11</sup>B elastic scattering system

New experimental data on the elastic scattering of the nuclear process 15N+11B at an energy of Elab=26.25 MeV were obtained on the DC-60 cyclotron of the INP RK. Based on a semi-microscopic analysis of the interaction of an accelerated 15N ion with 1p-shell nuclei 11B the effectiveness of the new B3Y-Fetal potential was studied. . The difference between the B3Y-Fetal potential and the traditional Yukawa potentials (M3Y-Reid and M3Y-Paris) is that its density-dependent parameters are determined from the saturation condition of nuclear matter at low energy. Analysis was performed on double folding optical model (DFOM) and so no for other acronyms. The real potential of semi-microscopic analysis was calculated on the matrix of effective NN - interactions by the density of nucleon distribution in the overlapping region of the colliding nuclei. The density C, α, β, γ - dependent parameters included in the effective NN interaction are calculated at the optimal K - incompressibility factor values. As a result of the analysis of the experimental data for the 15N+11B system, the optimal parameter values for the elastic scattering cross-section were determined. The effectiveness of the B3Y-Fetal potential used to increase the saturation property of the nuclear substance is determined by the Nr - renormalization factor of semi-microscopic analysis and the χ2/N - comparison factor with the experimental cross-section.
