Abstract: New experimental data for differential cross sections of ¹⁴С(¹¹B, ¹¹B)¹⁴С inelastic scattering at the energy E_lab.(¹¹В) = 45 MeV for transitions of ¹¹B nucleus to the excited states of 2.12 - 8.56 MeV were obtained. Experimental data were analyzed within optical model and coupled-reaction channels method. Elastic and inelastic scattering of nuclei, reorientation of spin of ¹¹B and simplest transfers of nucleons and clusters were included in the coupling scheme. Woods - Saxon optical model parameters of ¹⁴С + ¹¹B interaction and deformation parameters of ¹¹B nucleus were deduced. Optical potential, deduced from the fit of experimental data, is compared to the respective folding-potential, calculated by the method of double-folding. Isotopic differences of optical model potentials for ^12,13,14С + ¹¹B interaction, using the results of recent publications of ^12,13С + ¹¹B elastic and inelastic scattering at similar energies, were investigated. Contributions of one- and two-step transfers of nucleons and clusters into the elastic and inelastic channels of ¹⁴С + ¹¹B scattering were defined.

Keywords: heavy-ion scattering, optical model, coupled-reaction-channels method, spectroscopic amplitudes, optical potentials, reaction mechanisms.
