We discuss our present understanding of the incomplete fusion (ICF) reaction dynamics, the excitation function of six evaporation residues (ERs) have been measured in ¹⁶O + ¹⁵⁶Gd reaction at projectile energy range, E/A ~ 4.3-6.3 MeV/Nucleon. Some of the ERs are produced directly & indirectly (i.e. through pre-cursor), the pre-cursor contributions have been separated out from the measured cumulative cross-section with the help of Cavinato et al.¹. After correcting the pre-cursor contribution, the independent yield has been compared with the statistical model code PACE-2², which describes the fusion reaction cross section. In order to optimize the parameter of the code PACE-2 that reproduces the cross section of all the complete fusion (CF) channels like xn and /or pxn-channels. Using the same set of input parameters, cross section of the ERs populated via incomplete fusion (ICF) channels have been measured. The enhancement in the measured cross section of the ERs populated via ICF channels over the PACE-2 prediction have been measured, which indicates the occurrence of the break-up of projectile ¹⁶O into (¹²C+α) and/or (⁸Be+2α) leading to ICF reaction dynamics.

能量范围为4.3-6.3 MeV / A的16O + 156Gd反应中的弹丸破裂对融合的影响

我们讨论了我们目前对不完全融合（ICF）反应动力学的理解，在弹丸能量范围E / A〜4.3-6.3 MeV / Nucleon下，在¹⁶ O + ¹⁵⁶ Gd反应中测量了六个蒸发残基（ER）的激发功能。一些ER是直接或间接产生的（即通过前体），在Cavinato等人的帮助下，前体的贡献已从测量的累积横截面中分离出来。¹。校正前兆贡献后，将独立收益与统计模型代码PACE-2 ^{2进行比较}，它描述了聚变反应的截面。为了优化代码PACE-2的参数，该参数可再现所有完整融合（CF）通道（如xn和/或pxn-channels）的横截面。使用相同的输入参数集，已测量了通过不完全融合（ICF）通道填充的ER的横截面。已经测量了通过ICF通道填充的ER的测量横截面相对于PACE-2预测的增强，这表明发生了弹丸¹⁶ O分解为（¹² C +α）和/或（⁸ Be +2α）导致ICF反应动力学。
