Abstract / Description of output

This is the first study of P27 to measure both the β-delayed proton and β-delayed γ decays. While no new proton groups in the astrophysically interesting energy region of 300-400 keV were observed, a new upper limit on the proton branching of 0.16% was estimated. Several new γ-ray lines were observed, mainly coming from the isobaric analog state in Si27, which has been assigned a more accurate energy value of 6638(1) keV.
