Destruction of the cosmic γ-ray emitter ²⁶Al in massive stars: Study of the key ²⁶Al (n, p) reaction

NUCLEAR REACTIONS ²⁶Al(n, p)²⁶Mg, E=25 meV-150 keV highly intense pulsed neutron beam from high-flux beam n_TOF facility (CERN); measured E(p), I(p), σ(E) using ΔE-E Si detector system. ²⁶Mg; deduced energies of proton resonances, resonance strengths. ²⁶Al(n, p), T=0.01-5 GK; deduced stellar reaction rates, and compared to previous measurements, with theoretical predictions and with recommended values of the reactivity by NON-SMOKER code, and JINA-REACLIB v1.1 library. Relevance to production of ²⁶Al in massive stars, and its destruction by (n, p) and (n, α) reactions.
