Based on the research for 1.809 MeV γ-ray by space detector. It is concluded that there are about 2～3 M□ ~(26)Al in Milk Way Galaxy. All built galaxy models can not interpret this phenomenon. Someproposed that SNIa may be the new way to explain it and the reaction (~(16)O+~(14)N) is a important approachto form ~(26)Al. Therefor we will research this reaction using AMS technology and put forward the relevant Based on the research for 1.809 MeV γ-ray by space detector.
