$\mathbf{A \approx 20 - 50}$质量范围内$\mathbfα$诱导反应截面的研究进展
$\mathbfα$-induced reaction cross sections in the mass range $\mathbf{A \approx 20 - 50}$: a critical review
摘要：
在最近的综述中，显示在大多数情况下，在$A \approx 20 - 50$质量范围内，$α$诱导反应的横截面遵循一般和平滑的趋势。为了比较不同能量下不同靶的截面，使用了约化截面$σ_{\rm{red}}$和约化能量$E_{\rm{red}}$的方法。确定了4个离群值：$^{36}$ Ar和$^{40}$ Ar具有非常小的截面，$^{23}$ Na和$^{33}$ S具有非常大的截面。$^{23}$ Na的新数据在这次NPA-7会议上公布;与以前的数据相反，这些新数据符合一般系统学。此外，给出了天体物理反应率的最有效能量$E_0$（所谓的伽莫夫窗）与约化能量$E_{\rm{red}}$之间的关系。
英文摘要：
In a recent review it was shown that the cross sections of $α$-induced reactions in the $A \approx 20 - 50$ mass range follow a general and smooth trend in most cases. For comparison of cross sections of different targets at various energies the method of reduced cross sections $σ_{\rm{red}}$ and reduced energies $E_{\rm{red}}$ was used. Four outliers were identified: $^{36}$Ar and $^{40}$Ar with unusally small cross sections and $^{23}$Na and $^{33}$S with unusually large cross sections. New data for $^{23}$Na were presented at this NPA-7 conference; contrary to the previous data, these new data fit into the general systematics. In addition, a relation between the most effective energy $E_0$ for astrophysical reaction rates (the so-called Gamow window) and the reduced energy $E_{\rm{red}}$ is presented.
