Abstract

Background: A recent coupled-reaction-channel (CRC) study shows that the enhanced oscillation of the elastic 16O + 12C section at backward angles is due mainly to the elastic α transfer or the core exchange. Such a process gives rise to a parity-dependent term in the total elastic S matrix, an indication of the parity dependence of the 16O + 12C optical potential (OP).
Purpose: To explicitly determine the core exchange potential (CEP) induced by the symmetric exchange of the two 12C cores in the elastic sup>16</sup>O + 12C scattering at Elab = 132 and 300 MeV and explore its parity dependence.
Method: S matrix generated by CRC description of the elastic 16O + 12C scattering is used as the input for the inversion calculation to obtain the effective local OP that contains both the Wigner and Majorana terms.
Results: The high-precision inversion results show a strong contribution by the complex Majorana term in the total OP of the 16O + 12C system and thus provide for the first time a direct estimation of the parity-dependent CEP.
Conclusions: The elastic α transfer or exchange of the two 12C cores in the 16O + 12C system gives rise to a complex parity dependence of the total OP. This should be a general feature of the OP for the light heavy-ion systems that contain two identical cores.
