Fusion phenomena in heavy-ion reactions involving all kinds of projectile and target are still an engrossing quest due to the appearance of numerous mass and energy sharing processes. Hitherto, it is required to have more experimental studies to contemplate fusion mechanisms, which are necessary to unfold. In this endeavour, for the first time, a measurement of residual cross sections from \(^6\)Li induced reaction on \(^{\text {nat}}\)Cu has been presented in this article within the 3.6–7.1 MeV/nucleon energy range. The residues \(^{69,67,66}\)Ge, \(^{68,67,66,65}\)Ga, and \(^{65,63,62}\)Zn produced in the reaction have been identified by the \(\gamma \)-ray spectroscopy. The measured excitation function of the residues has been analyzed using equilibrium and pre-equilibrium reaction models in the framework of PACE4, EMPIRE-3.2.2 and ALICE20 to understand the reaction mechanisms involved in the low energy region. The study indicates that the admixture of equilibrium and pre-equilibrium mechanisms indeed explains the measured residual cross sections. An estimate on the production of medically relevant \(^{68}\)Ga has also been made.

由于大量质量和能量共享过程的出现，涉及各种射弹和目标的重离子反应中的聚变现象仍然是一项引人入胜的探索。迄今为止，需要进行更多的实验研究来思考融合机制，这是展开所必需的。在这项努力中，本文首次在 3.6–7.1 中介绍了对\(^{\text {nat}}\) Cu上\(^ 6\) Li 诱导反应的残余横截面的测量MeV/核子能量范围。反应产生的残基\(^{69,67,66}\) Ge、\(^{68,67,66,65}\) Ga和\(^{65,63,62}\) Zn已由\(\gamma \)识别-射线光谱。在PACE4、EMPIRE - 3.2.2和ALICE20的框架下，使用平衡和预平衡反应模型分析了残留物的测量激发函数，以了解低能量区域中涉及的反应机制。研究表明，平衡和预平衡机制的混合确实解释了测量的残余横截面。还对医学相关\(^{68}\) Ga 的产生进行了估计。
