Abstract

Several resonances in 25Al(p,γ) 26Si have been studied via the 28Si(p,t) 26Si reaction. Triton energies and angular distributions were measured using a segmented annular detector array. An additional silicon detector array was used to simultaneously detect the coincident protons emitted from the decay of states in 26Si above the proton threshold in order to determine branching ratios. A resonance at 5927 ± 4 keV has been experimentally confirmed as the first ℓ = 0 state above the proton threshold, with a proton branching ratio consistent with one.
