论文摘要
我们讨论了靶核在$^{15} $ c + $^{232} $ th系统在库仑屏障周围的能量系统的融合反应中的变形的作用，$^{15} $ c是一个众所周知的单个单位halo核。为此，假设弹丸核由核心核组成，$^{14} $ c和价值中子，我们将使用双折叠过程构建$^{15} $ c和$^{232} $ th之间的电势。通过考虑弹丸核的光环性质以及目标核的变形，我们同时重现了$^{14} $ c + $ c + $^{232} $ th和$^{15} $ c + $ c + $^{232} $ th Systems的融合横截面。我们的计算表明，该系统的分解和传输通道的净效应很小。
We discuss the role of deformation of the target nucleus in the fusion reaction of the $^{15}$C + $^{232}$Th system at energies around the Coulomb barrier, for which $^{15}$C is a well-known one-neutron halo nucleus. To this end, we construct the potential between $^{15}$C and $^{232}$Th with the double folding procedure, assuming that the projectile nucleus is composed of the core nucleus, $^{14}$C, and a valance neutron. By taking into account the halo nature of the projectile nucleus as well as the deformation of the target nucleus, we simultaneously reproduce the fusion cross sections for the $^{14}$C + $^{232}$Th and the $^{15}$C + $^{232}$Th systems. Our calculation indicates that the net effect of the breakup and the transfer channels is small for this system.
