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 ⁶Li + ⁹⁴Zr system were measured at the energies around the Coulomb barrier by online γ-ray method. In addition to a 30% suppression factor when compared with the measured total fusion process, the complete fusion cross section in ⁶Li + ⁹⁴Zr system was observed to be significantly lower than those in the nearby ⁶Li + ^{90, 96}Zr system. The new experimental result implies that the coupling with breakup channel in the ⁶Li-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 ⁹⁵Zr 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 ⁶Li.
