Revised decay properties of the key 93-keV resonance in the ²⁵Mg(p, γ) reaction and its influence on the MgAl cycle in astrophysical environments

NUCLEAR REACTIONS ¹¹B(¹⁶O, n), E=19 MeV; measured Eγ, Iγ, γ(θ), γγγ-coin. ²⁶Al; deduced levels J, π, branchings. Obtained ground state branching for 93-keV resonance of ²⁵Mg+p system which corresponds to 6398 keV level in ²⁶Al. Comparison to other experimental data. Discussed impact on the production of cosmic γ rays. Gammasphere array with 99 detectors at ATLAS accelerator (ANL).
