Abstract

The γ-decay of 60 and the strengths of 51 26Mg(p, γ)27Al resonances were studied for Ep < 2.20 MeV. The energies of 32 and the γ-decay of 54 bound levels were determined. Spin and parity assignments Jπ = 52+, 52, 32, 32+, 32+ and 32+ were made to the bound states at Ex = 4.81, 5.44, 6.61, 6.78, 7.68 and 7.86 MeV, respectively. Spin assignments J = 52and 32 were made to the bound levels at Einx = 5.55 and 6.08 MeV, respectively. For other levels spin and parity limitations were set. Lifetimes or lifetime upper limits of 19 bound levels were measured by means of the DSA technique. The spins and/or parities of 15 resonances were unambiguously determined from γ-ray angular distributions and strengths.

      For example, consider the level scheme of 27Al shown in Fig. 1. An inspection of primary γ-ray branching ratios for resonances below ER=3.0 MeV in the 26Mg+p reaction (Qpγ=8.27 MeV) reveals that the majority of γ-ray decays proceed to the five lowest-lying levels in 27Al with excitation energies of Ex<3.0 MeV [1,13]. Similar arguments hold for (p,γ) reactions on other target nuclei in the sd-shell [14,15].
