Evaporation residue (ER) cross-sections were measured for ³⁰Si+¹⁴²Ce reaction at laboratory energies in the range of 105 - 132 MeV using the HYbrid Recoil mass Analyzer (HYRA) at IUAC, New Delhi. The transmission efficiency of the HYRA was estimated using the calibration reaction ²⁸Si+¹⁴²Ce. Sub-barrier fusion enhancement was observed when compared with the one-dimensional barrier penetration model predictions for the present system. To explore the phenomena responsible for sub-barrier fusion enhancement, coupled-channels calculations were performed using the CCFULL code. The effect of couplings and the role of positive Q-value neutron transfer (PQNT) channels on sub-barrier fusion cross-sections were investigated. Coupled-channels calculations were able to reproduce the data by including the coupling in both projectile and target nucleus along with two neutron-transfer channels having positive Q-value. The measured ER cross-sections were compared with the nearby systems to explore the role of deformation of the colliding nuclei.

使用新德里 IUAC 的 HYbrid 反冲质量分析仪 (HYRA) 在 105 - 132 MeV 范围内的实验室能量下测量³⁰ Si+ ¹⁴² Ce 反应的蒸发残留物 (ER) 横截面。^{使用校准反应28} Si+ ¹⁴² Ce估算 HYRA 的传输效率。与本系统的一维势垒穿透模型预测相比，观察到了子势垒融合增强。为了探索亚势垒融合增强的现象，使用 CCFULL 代码进行耦合通道计算。研究了耦合效应和正Q值中子转移 (PQNT) 通道对亚势垒聚变截面的作用。耦合通道计算能够通过包括射弹和靶核中的耦合以及具有正Q值的两个中子传递通道来重现数据。将测得的电流变截面与附近的系统进行比较，以探索碰撞核变形的作用。
