星际²⁶Al核合成的研究进展

摘要: 介绍了星际 26Al衰变所发射1 809 keV γ射线的最新空间探测结果，综述了目前关于星际 26Al起源的各种天体模型的研究进展。最后，简要阐述了14N(p,γ)15O反应截面的最新测量结果及其对 26Al起源研究的影响，探讨了一种星际 26Al合成的可能新途径。
The recently detection outcome about interstellar 26Al is introduced, as well as the investigation progresses of interstellar 26Al nucleosynthesis in all models are reviewed. Finally, the new nuclear physics experimental results for the14N(p,γ)15O reaction effect on sources of interstellar 26Al and an alternative new way for nucleosynthesis 26Al in SNIa are discussed.
