摘要

Motivated by the cluster structure of 13C, where a 12C core is coupled with a neutron at an excitation energy of 4.946 MeV, we investigated the effects of single-nucleon transfer between 13C and 12C nuclei. The neutron stripping transfer reaction, 12C(13C,12C)13C, was studied at center-of-mass energies (Ec.m.) ranging from 7.8 to 49.14 MeV. We analyzed both elastic scattering and elastic transfer data using the optical model (OM) and the Distorted Wave Born Approximation (DWBA). The analysis incorporated a cluster folding potential, which accounts for the cluster nature of the 13C nucleus—comprising a 12C core with a valence neutron orbiting around it. Our results show reasonable agreement with the experimental data across the entire energy range. Furthermore, we extracted the spectroscopic amplitude for the 13C → 12C + n configuration, and the obtained values are consistent with previously reported results.
