从捕获和准弹性后向散射激发函数提取的捕获概率之间的不一致
Disagreement between capture probabilities extracted from capture and quasi-elastic backscattering excitation functions
摘要：
重离子反应的s波俘获几率通常由实验上的准弹性背散射和俘获（聚变）激发函数来提取。我们研究了$^{16}$ O+ $^{120}$ Sn，$^{144}$ Sm，$^{208}$ Pb体系在相应的库仑势垒附近和以下的能量，并得出结论，在亚和深亚势垒能量下，从准弹性数据提取的几率比从熔合激发函数提取的几率大得多.这似乎是一个合理的解释，在文献中观察到的分歧来自两种方法的核势扩散。
英文摘要：
Experimental quasi-elastic backscattering and capture (fusion) excitation functions are usually used to extract the s-wave capture probabilities for the heavy-ion reactions. We investigated the $^{16}$O+$^{120}$Sn,$^{144}$Sm,$^{208}$Pb systems at energies near and below the corresponding Coulomb barriers and concluded that the probabilities extracted from quasi-elastic data are much larger than the ones extracted from fusion excitation functions at sub and deep-sub barrier energies. This seems to be a reasonable explanation for the known disagreement observed in literature for the nuclear potential diffuseness derived from both methods.
