Abstract

The angular distributions of elastic and inelastic scattering of the 14N ions on the 12C nuclei at the energy E ( 14N) = 116 MeV for the transitions to the 4.44 MeV (2 +) excited state of 12C and to the 3.95 MeV (1 +), 4.915 MeV (0 −) +5.11 MeV (2 −) excited states of 14N as well as the 12C( 14N, 13C) 13N, 12C( 14N, 13N) 13C and 12C( 14N, 12C) 14N transfer reactions were measured. The experimental data were analyzed using the coupled reaction channels (CRC) model. All measured quasi-elastic channels were included in the coupling scheme of the CRC calculation. The strong coupled-channel effects were observed. The optical model potentials for the 12C+ 14N and 13C + 13N channels were deduced. The deformation parameters for the 12C and 14N nuclei were obtained from the CRC analysis of inelastic scattering. The isotopic effects in the 14N ion scattering off the 12C and 14C targets were investigated. Both one- and two-step processes were studied for transfer channels. It was found that two-step transfers give significant contributions to some reaction channels. Good description of all experimental data was achieved.
