论文摘要
将$^{17} $ f + $^{12} $ C的实验性上栏融合横截面与$^{16,18} $ O，$^{19} $ f的融合激发功能进行比较。在比较不同的系统时，通过检查减少的融合横截面来解释入射离子的不同静态大小和融合屏障的变化。观察到融合横截面的剩余趋势，这反映了SD质子和中子的敏感相互作用。还将实验数据与广泛使用的近级融合的分析模型以及时间依赖的Hartree-Fock模型进行了比较。两种模型都无法描述观察到的趋势。
Experimental above-barrier fusion cross-sections for $^{17}$F + $^{12}$C are compared to the fusion excitation functions for $^{16,18}$O, $^{19}$F, and $^{20}$Ne ions on a carbon target. In comparing the different systems both the differing static size of the incident ions and changes in fusion barrier are accounted for by examining the reduced fusion cross-section. Remaining trends of the fusion cross-section above the barrier which reflect the sensitive interplay of the sd protons and neutrons are observed. The experimental data are also compared to both a widely-used analytical model of near-barrier fusion, as well as a time-dependent Hartree-Fock model. Both models fail to describe the trends observed.
