Elastic and inelastic scattering of 15N ions by 10B at energy 81 MeV. Isotopic effects in scattering of 15N + 10В, 15N + 11В, 14N + 10В nuclei

Abstract

New experimental data of angular distributions for the elastic and inelastic scattering of 15N ions by 10B nuclei were obtained at the energy Elab(15N) = 81 MeV. The experimental data were analyzed within the coupled-reaction channels method (CRC). The Woods - Saxon optical potentials were used for nuclei interactions in the calculations. The potential's parameters for the interaction of 15N + 10В nuclei were deduced as well as it was measured the angular distribution of the elastic scattering for these nuclei. The experimental data of the 15N + 10В elastic scattering are compared with data of the 15N + 11В and 14N + 10В scatterings. It was discovered isotopic effects in the scatterings of these three nuclear couples due to the difference in the optical potentials of the interaction of these nuclei and their structure. New experimental data of inelastic scattering of 15N + 10В nuclei for 0.718 - 3.587 МеV states of 10В nucleus and for 5.270 - 6.324 МеV states of 15N nucleus were measured. These data were analyzed within the CRC method using the translation-invariant shell model for collective excitations of 15N and 10B nuclei. Information about deformations of these nuclei was obtained.
