An experiment has been performed for the measurements of forward recoil range distributions (FRRDs) of evaporation residues (ERs) using ¹⁶O beam on the target ¹⁴⁸Nd to explore the incomplete fusion (ICF) dynamics at low projectile energy ≈ 4-6 MeV/A. In the present work, FRRDs of ERs ^159,158Er(xn), ^160g,159Ho(pxn), ^157,155Dy(αxn) and 155Tb(αpxn) have been measured. The measured FRRDs of ERs have been compared with their theoretical mean ranges, calculated using code SRIM. These present results obtained from FRRDs measurements show that full and partial linear momentum transfer components are involved. This indicates that the ERs populated through α-emission channels are not only produced via complete fusion, but also through incomplete fusion dynamics. The present analysis indicates that the incomplete fusion contribution increases with projectile energy. This increment in incomplete fusion contribution is due to the increase in breakup probability of projectile ¹⁶O into ¹²C + ⁴He/ α with projectile energy.

解开低能量≈4-6 MeV / A时不完全融合的动力学

在目标¹⁴⁸ Nd上使用¹⁶ O光束对蒸发残余物（ER）的前向后坐力范围分布（FRRD）进行了实验，以探索低弹能量≈4-6 MeV /下的不完全融合（ICF）动力学一种。在目前的工作中，ER的^{FRRD 159,158} Er（xn），^160g，159 Ho（pxn），^157,155Dy（αxn）和155Tb（αpxn）已被测量。已将测得的ER的FRRD与使用代码SRIM计算的理论均值范围进行了比较。从FRRD测量获得的这些当前结果表明，涉及全部和部分线性动量传递分量。这表明通过α-发射通道填充的ER不仅通过完全融合产生，而且还通过不完全融合动力学产生。目前的分析表明，不完全融合的贡献随着射弹能量的增加而增加。这种不完全融合贡献的增加是由于弹丸能量使弹丸¹⁶ O分解为¹² C + ⁴ He /α的可能性增加。
