We performed a new measurement of the 26Al(n, α) reaction up to 160-keV neutron energy at the neutron time-of-flight facilities n_TOF at CERN and GELINA at EC-JRC. We provide strengths for ten resonances, six of them for the first time. We use our data to calculate astrophysical reactivities for stellar temperatures up to 0.7 GK. Our results resolve a discrepancy between the two previous direct measurements of this reaction, and indicate higher stellar destruction rates than the most recently recommended reactivity.}, organization = {Austrian Science Fund (FWF) J3503}, organization = {JRCIRMM through the EUFRAT Program}, organization = {UK Research & Innovation (UKRI)}, organization = {Science & Technology Facilities Council (STFC) ST/L005824/1 ST/M006085/1}, organization = {European Research Council (ERC)}, organization = {European Commission 677497}, organization = {Cost Action "ChETEC" CA16117}, publisher = {American Physical Society}, title = {Destruction of the cosmic γ-ray emitter 26Al in massive stars: Study of the key 26Al(n, α) reaction}, doi = {10.1103/PhysRevC.104.L032803}, author = {Lederer Woods, C. and Porras Sánchez, José Ignacio and Praena Rodríguez, Antonio Javier and TOF Collaboration}, }
