$^{9}$ Be弹与不同靶点的融合及其抑制

Understanding fusion and its suppression for the $^{9}$Be projectile with different targets

V. Jha, V. V. Parkar, S. Kailas

摘要:

研究了弱束缚粒子$^{9}$ Be在$^{28}$ Si、$^{89}$ Y、$^{124}$ Sn、$^{144}$ Sm和$^{208}$ Pb靶上的分裂过程和一个中子剥离对近垒熔合的作用。用连续离散耦合通道(CDCC)方法计算了$^{8}$ Be核的分裂过程,用耦合反应通道(CRC)方法计算了靶中一个中子剥离成多个单粒子态的过程.从CDCC-CRC计算得到的所有系统的库仑势垒以上的实验熔合截面的一个很好的描述。不同的目标系统的计算不完全融合概率被发现是一致的系统行为的完整的融合抑制因子作为目标原子质量的函数,从实验数据中获得。

英文摘要:

The role of the breakup process and one neutron stripping on the near barrier fusion are investigated for the weakly bound projectile $^{9}$Be on $^{28}$Si, $^{89}$Y, $^{124}$Sn, $^{144}$Sm and $^{208}$Pb targets. Continuum-discretized coupled channels (CDCC) calculations for the breakup with a $^{8}$Be + n model of the $^{9}$Be nucleus and coupled reactions channels (CRC) calculations for the one neutron stripping to several single particle states in the target are performed for these systems. A good description of the experimental fusion cross sections above the Coulomb barrier is obtained from the CDCC-CRC calculations for all the systems. The calculated incomplete fusion probabilities for different target systems are found to be consistent with the systematic behaviour of the complete fusion suppression factors as a function of target atomic mass, obtained from the experimental data.
