Identification of analog states in the T = 1/2 A = 27 mirror system from low excitation energies to the region of hydrogen burning in the ²⁶Al^{g, m}(p, γ)²⁷Si reactions

NUCLEAR REACTIONS ¹²C(¹⁶O, p), E=26 MeV; measured Eγ, Iγ, γγ-coin, γ(θ), level half-lives by DSA method using Gammasphere array. ²⁷Al; deduced levels, J, π, multipolarities, mirror energy differences. Comparison with shell-model calculations, and with level structure of ²⁷Si mirror nucleus. Relevance to ²⁶Al(p, γ)²⁷Si and ^26mAl(p, γ)²⁷Si reactions for galactic abundance of the cosmic ^26gAl, and for the excess abundance of ²⁶Mg in presolar grains.
