Abstract: New experimental data of angular distribution cross-sections for the ¹⁰В(¹⁵N,¹⁴С)¹¹С reaction at the energy Е_lab(¹⁵N) = 81 MeV were obtained for the ground states of ¹⁴С, ¹¹С nuclei and 2.00 MeV (1/2^-), 4.31 MeV (5/2^-), 4.31 MeV (3/2^-) excited states of ¹¹С nucleus. The experimental data were analyzed within the coupled-reaction-channels (CRC) method. In the CRC calculations, the ¹⁵N + ¹⁰В Woods - Saxon (WS) optical potential obtained from the CRC analysis of the experimental elastic and inelastic data of these nuclei was used and parameters of the ¹⁴С + ¹¹С WS optical potential were deduced from the analysis of the ¹⁰В(¹⁵N,¹⁴С)¹¹С reaction experimental data. Spectroscopic amplitudes of nucleons and cluster transfers were calculated within the translation-invariant shell model.

Keywords: nuclear reaction ¹⁰В(¹⁵N,¹⁴С)¹¹С, Е_lab(¹⁵N) = 81 MeV, σ(θ), particle spectra of ¹¹C and ¹⁴C, the Woods - Saxon optical potential of ¹⁴C + ¹¹C nuclei interaction.
