Abstract

Measurements of the γ-ray decay and angular distributions at eight low-energy (Ep < 1 MeV) 26Mg(p, γ)27Al resonances lead to the spin and parity assignments Jπ = 32+, 12, 32, 52+, 52, 32, 32, 9/2 and 7/2 for the bound states at Ex = 3.96, 4.05, 5.16, 5.25, 5.44, 6.16, 6.99, 7.23 and 7.48 MeV, respectively. For other levels, spin and parity limitations are set. Also reported are precise excitation energies, branching and mixing ratios, and lifetime limits. For the resonances additional information is given on energies, strengths and widths. The reaction Q-value is Q = 8271.0 ± 0.5 keV. The level scheme of 27Al, complemented with these new data, is compared with the results from recent shell-model calculations.
