天体物理学重要核$^{26}$ Mg能级的高分辨率研究和最新能级分配
A high-resolution study of levels in the astrophysically important nucleus $^{26}$Mg and resulting updated level assignments
摘要：
$^{22}$ Ne（$α,n$）$^{25}$ Mg反应是s过程的重要中子源。由于难以直接测量该反应和竞争的$^{22}$ Ne（$α,γ$）$^{26}$ Mg反应的截面，因此经常使用间接方法来尝试计算相关的反应速率。然而，不确定性仍然存在于$^{26}$ Mg的相关激发态的数量和性质中。本文给出了质子和氘核在$^{26}$ Mg中散射的结果，给出了$^{26}$ Mg中的能级列表。此外，在$^{26}$镁的水平分配进行了讨论，包括一些可能的变化，以前接受的分配$^{26}$镁。
英文摘要：
The $^{22}$Ne($α,n$)$^{25}$Mg reaction is an important source of neutrons for the s-process. Due to the difficulty in directly measuring the cross section of this reaction and the competing $^{22}$Ne($α,γ$)$^{26}$Mg reaction, indirect methods are frequently used to try to instead calculate the relevant reaction rates. Uncertainty, however, persists in the number and properties of the pertinent excited states of $^{26}$Mg. In this paper, the results of proton and deuteron scattering from $^{26}$Mg are presented, giving a list of levels in $^{26}$Mg. In addition, level assignments in $^{26}$Mg are discussed, including some possible changes to the previously accepted assignments in $^{26}$Mg.
