- Abstract
- The N-13+C-12 and C-13+C-12 elastic cross sections are measured at the center-of-mass energies of 7.8, 9.6, and 14.2 MeV, using radioactive N-13 and stable C-13 beams and position-sensitive solid-state detectors. These data are analyzed with the optical model assuming the same real central part of the nuclear potential for both systems as suggested by charge symmetry. The N-13+C-12 angular distributions display a significant backward rise which arises from a parity dependence of the nucleus-nucleus interaction, as for the mirror C-13+C-12 system. The corresponding parity terms in both potentials are similar when the different charges of the exchanged nucleons and their different binding energies are properly taken into account. A smaller imaginary part is obtained for N-13+C-12 than for C-13+C-12, which might be due to a smaller number of open-two-body inelastic and direct reaction channels.
