¹²С(¹⁵N, ¹⁴С) ¹³N reaction mechanisms at energy 81 MeV and ¹⁴С + ¹³N nuclei interaction

The ¹²С(¹⁵N, ¹⁴С) ¹³N reaction at the energy Е_lab (¹⁵N) = 81 MeV for ground and excited states of ¹⁴С and ¹³N nuclei was investigated. New experimental data of the reaction cross-sections were obtained. The data were analyzed within the coupled reaction channels method (CRC). The ¹⁵N + ¹²С elastic scattering as well as the more important reactions of nucleon and cluster transfers were included in the channels-coupling scheme. In the CRC-calculations, the Woods - Saxon potentials (WS) were used for the interactions of ¹⁵N + ¹²С and ¹⁴С + ¹³N nuclei in the entrance and exit reaction channels. WS potential parameters for the reaction entrance channel were deduced previously from CRC-analysis of the ¹⁵N + ¹²С elastic and inelastic scattering data, then the WS potential parameters for the reaction exit channel were deduced from the fitting of ¹²С(¹⁵N, ¹⁴С) ¹³N reaction data. The spectroscopic amplitudes of nucleons and clusters, used in the CRC-calculations, were computed within translational invariant shell model. As the results of the reaction CRC-analysis, the information about WS potential of ¹⁴С + ¹³N nuclei interaction as well as about mechanisms of nucleons and clusters transfer was deduced. It was found, that transfers of protons and 2n-clusters dominate in this reaction. It was also studied the differences of the reaction CRC cross-sections calculated using the ¹⁴С + ¹³N і ¹⁴С + ¹⁴N potentials in the reaction exit channel (isotopic effects).
