Radiative Decay of Some Low-Lying States ofMg27

Abstract

The gamma-ray de-excitation of several low-lying states of ${\mathrm{Mg}}^{27}$ has been observed by measuring proton-gamma-ray coincidences. The levels in ${\mathrm{Mg}}^{27}$ were populated using the ${\mathrm{Mg}}^{26}(d, p){\mathrm{Mg}}^{27}$ reaction. The results are as follows: the 0.984-MeV level decays to the ground state 100%; the 1.69-MeV level decays to the ground state 100% with no observed transition to the 0.984 state (limit
