E(level): Up to 3433.0 keV level, deduced from a least-squares fit to the measured γ-ray energies in 29Mg β- decay, ΔE=1 keV is assumed. Above 3433.0 keV, level energies are from 27Al(t,p),26Mg(α,pγ) dataset.
Jπ(level): From L value in 27Al(t,p) and target (27Al) Jπ=5/2+. Additional arguments are noted as comments.
T1/2(level): From 26Mg(α,pγ), except otherwise noted.
E(γ): Calculated by the evaluator from level energy differences, Ei-Ef and recoil energy subtracted.
M(γ): From 26Mg(α,pγ) dataset and parity of multipole radiation is assigned by the evaluator based on the RUL.
