The γ-ray emission associated with the radioactive decay of 26Al is one of the key pieces of observational evidence indicating stellar nucleosynthesis is an ongoing process in our Galaxy, and it was the first such radioactivity to be detected. Despite numerous efforts in stellar modeling, observation, nuclear theory, and nuclear experiment over the past four decades, the precise sites and origin of Galactic 26Al remain elusive. We explore the present experimental knowledge concerning the destruction of 26Al in massive stars. The precise stellar rates of neutron-induced reactions on 26Al, such as (n,p) and (n,α), have among the largest impacts on the total 26Al yield. Meanwhile, reactions involving the short-lived isomeric state of 26Al such as radiative proton capture are highly-uncertain at present. Although we presented on-going experimental work from n TOF at CERN with an 26Al target, the present proceeding focuses only on the 26Al isomeric radioactive beam production aspect and the first experimental results at CRIB.
