论文摘要
我们应用了厚目标逆运动学方法，以研究通过中子发射衰减的共振。作为一个测试，我们使用了经过良好研究的，因为它在恒星中的S过程中的作用，$^{13} $ c（$α$; n）反应。 $^{13} $ c（$α$; n）激发功能的观察到的能量分辨率为$ \ sim $ 60 kev，这是梁的时间结构和中子检测器的厚度最大的最大贡献。这些测量结果证明了该方法的效率很高，并揭示了基于最新先前分析的参数与R-Matrix计算的分歧。
We applied Thick Target Inverse Kinematics Method for a study of resonances decaying through neutron emission. As a test we used a well-studied, because of its role in s-process in stars, $^{13}$C($α$; n) reaction. The observed energy resolution for the $^{13}$C($α$; n) excitation function was $\sim$60 keV, the largest contributions coming from the time structure of the beam and the thickness of the neutron detector. These measurements demonstrated the high efficiency of the approach and revealed a disagreement with R-matrix calculations based on parameters of the most recent previous analysis.
