介绍了星际^26Al衰变所发射1809keVγ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 the ^14N(p,γ)^15O reaction effect on sources of interstellar ^26Al and an alternative new way for nucleosynthesis ^26Al in SNIa are discussed.
