Abstract
The reaction26Mg(p, γ)27Al has been investigated atE p (lab)=80–355 keV. The existence of the resonances atE p =292 and 338 keV has been verified and new resonances were found atE p =227 and 275 keV. Information on branching and mixing ratios,ωγ values, total widths, andJ π assignments for the observed resonances is given. Upper limits on theωγ strengths for expected resonances in the energy range covered are presented. The astrophysical aspects of the data are discussed in the light of the26Mg(26Al) isotopic anomaly.
