论文摘要
一个中子剥离横截面对总反应横截面的贡献已在$^{169} $ tm，$^{181} $ ta，$^{181} $ ta，$^{187} $ re和$^{197} $ au目标周围的库仑障碍物周围的目标。将这些系统的一个测量的一个中子剥离横截面与耦合的通道计算进行了比较。在本计算中使用了最近开发的全局光学模型潜在参数。发现了测得的完整融合（CF），不完整融合（ICF），一个中子剥离和计算出的非捕获分裂（NCBU）横截面的累积，可以解释几乎所有目标的反应横截面。目标非弹性状态和弹性分解的贡献很小，可能会导致其余部分。 CF，ICF，一个中子剥离和反应横截面的NCBU的横截面的百分比百分比显示了中子转移和NCBU在低于屏障能量下的优势，而CF和ICF工艺在上面的屏障能中具有主要的贡献。
The contribution of one neutron stripping cross section to the total reaction cross section has been studied for $^9$Be projectile incident on $^{169}$Tm, $^{181}$Ta, $^{187}$Re and $^{197}$Au targets around Coulomb barrier energy. The measured one neutron stripping cross sections for these systems have been compared with the coupled channel calculations. The recently developed global set of optical model potential parameters for $^9$Be projectile has been used in the present calculations. The cumulative of measured complete fusion (CF), incomplete fusion (ICF), one neutron stripping and calculated non-capture breakup (NCBU) cross sections is found to explain almost the reaction cross sections for all the targets. A very small contribution from target inelastic states and elastic breakup may contribute to the remaining part. The percentage fraction of cross section for CF, ICF, one neutron stripping, and NCBU over reaction cross section show the dominance of neutron transfer and NCBU at below barrier energies while CF and ICF processes have the major contribution at above barrier energies.
