摘要：
The reaction25Mg(p,γ)26Al has been investigated at Ep(lab)=80-350keV. The existence of the resonance at Ep=317keV has been verified and new resonances have been found at Ep=198, 255 and 304 keV. The Ep = 304keV resonance represents a new compound state in26A1. Information on branching ratios, Ωγ values, total widths and Jπ assignments for the observed resonances as well as upper limits on the my strengths for the expected resonances at Ep=97 and 134 keV are given. The astrophysical aspects of the data are discussed in the light of the renewed interest in the precise location of26A1 nucleosynthesis. © 1979 Springer-Verlag.
