Two-step process in the 12C(d, p)13C reaction

The differential cross sections for the 12C(d, p)13C reaction at a deuteron energy of 9.0 MeV have been measured with paying special attention to the transitions to the 5/2+ state at 6.864 MeV and the 3/2+ state at 7.677 MeV. The experimental results were compared with the second-order DWBA calculations that involve the inelastic excitation of 12C core using coupled channel form factors. The theoretical calculations reproduce the experimental data well. It has been shown that the two-step processes are dominant in the 12C(d, p)13C reaction leading to these states that have large fractions of the parentage of the excited state of target nucleus.
