丰中子中等质量核聚变中振动、转动和中子转移作用的解开
Disentangling the role of vibration, rotation, and neutron transfer in the fusion of neutron-rich mid-mass nuclei
摘要：
我们首次测量了$^{39,47}$ K + $^{28}$ Si在近垒能区的熔合激发函数。蒸发残留物从融合过程中产生的确定直接测量其能量和飞行时间具有高的几何效率。在最低入射能量下，富中子$^{47}$ K诱导反应的截面比$β$稳定系统的截面大约6倍。实验数据进行了比较与动态变形模型和耦合通道计算（CCFULL）。
英文摘要：
We report the first measurement of the fusion excitation functions for $^{39,47}$K + $^{28}$Si at near-barrier energies. Evaporation residues resulting from the fusion process were identified by direct measurement of their energy and time-of-flight with high geometric efficiency. At the lowest incident energy, the cross-section measured for the neutron-rich $^{47}$K induced reaction is ~6 times larger than that of the $β$-stable system. The experimental data are compared with both a dynamical deformation model and coupled channels calculations (CCFULL).
