Fusion and one-neutron stripping process for 6Li+94Zr system around the Coulomb Barrier

The complete and incomplete fusion cross section as well as one-neutron stripping process of Li-6 + Zr-94 system were measured at the energies around the Coulomb barrier by online gamma-ray method. In addition to a 30% suppression factor when compared with the measured total fusion process, the complete fusion cross section in Li-6 + Zr-94 system was observed to be significantly lower than those in the nearby Li-6 + Zr-90,Zr- 96 system. The new experimental result implies that the coupling with breakup channel in the Li-6-induced fusion processes can be affected by the inner structure of the target, which is still not clear in any available model calculation. For the one-neutron stripping process, the direct production cross sections for each level in Zr-95 were extracted and compared with the coupled reaction channel calculation, offering a unique opportunity to examine the single-particle nature of the produced excited states. Given the fact that an overall overestimation of the production cross section for 954-keV and 1618-keV levels was observed in the comparison, further investigation is highly demanded in order to understand the full reaction mechanism for the one-neutron stripping process induced by Li-6.
