Abstract: New experimental data of angular distributions for the elastic and inelastic scattering of ¹⁵N ions by ¹⁰B nuclei were obtained at the energy E_lab(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.

Keywords: nuclear reactions ¹⁰В(¹⁵N,¹⁵N)¹⁰В, Е = 81 MeV, particle spectra of ¹⁰В and ¹⁵N, δ(θ), potential of ¹⁰В + ¹⁵N nuclei interaction, deformations of ¹⁰В and ¹⁵N nuclei.
