首次测量了$^{21}$O + $^{12}$C的融合激发函数，并将其与中子丰度较低的同位素的融合情况进行对比，研究了d$_{5/2}$壳层价中子对融合激发函数的影响。实验数据表明，提取的势垒高度$V_B$和势垒位置$R_B$明显依赖于中子过剩量。为评估动力学的作用，将实验数据与密度约束冻 Hartree-Fock（DCFHF）理论、密度约束含时 Hartree-Fock（DCTDHF）理论进行了对比。
英文摘要
The fusion excitation function for $^{21}$O + $^{12}$C was measured for the first time and compared to the fusion of less neutron-rich isotopes. The impact of valence neutrons in the d$_{5/2}$ shell on the fusion excitation function is examined. The experimental data manifest a clear dependence of the extracted barrier height, V$_B$, and barrier position, R$_B$ on neutron excess. To assess the role of dynamics the experimental data are compared with both density constrained frozen Hartree Fock (DCFHF) and density constrained time-dependent Hartree Fock (DCTDHF) theories.
