虽然22Ne(α，n)25 mg反应被认为是大质量恒星这一过程的重要中子源，但竞争22Ne(α，γ)26 mg反应可能具有相当大的强度，并可能显著抑制中子产生。为了更好地理解这一中子源，应通过实验测定n和γ部分宽度(Γn，Γγ)的分支比以及伽莫窗口(Eα=400-1000keV)内26 MG共振态的能量和自旋等光谱信息。在本工作中，我们建议使用6Li(22Ne，26 mg)dα转移反应来研究这些共振参数，并测试了实验的可行性。
While the reaction22Ne(α,n)25Mg is considered an important neutron source for thesprocess in massive stars, the competing22Ne(α,γ)26Mg reaction may be of considerable strength and could significantly suppress the neutron production. For a better understanding of this neutron source, the branching ratio of n andγpartial widths (Γn, Γγ) and spectroscopic information such as energies and spins of26Mg resonance states within the Gamow window (Eα= 400-1000 keV) should be experimentally determined with improved accuracy. In the present work, we propose to use the6Li(22Ne,26Mg)dα-transfer reaction to investigate those resonance parameters and have tested the feasibility of the experiment.
