Abstract
The 6Li+89Y experiment was performed to explore the reaction mechanism induced by a weakly bound nucleus 6Li and its cluster configuration. The particle-γ coincidence method was used to identify the different reaction channels. The γ-rays coincident with 3He/3H indicate that the 3H/3He stripping reaction plays a significant role in the formation of Zr/Nb isotopes. The obtained results support the existence of a 3He–3H cluster in 6Li. Direct and sequential transfer reactions are adequately discussed, and the FRESCO code is used to perform precise finite-range cyclic redundancy check calculations. In the microscopic calculation, direct cluster transfer is more predominant than sequential transfer in 3H transfer. However, the direct cluster transfer is of comparable magnitude to the sequential transfer in the 3He transfer.
