Abstract Determining the stellar production site of 26Al is an exciting problem that spans experimental and theoretical nuclear physics, astrophysics, and observational astronomy. This thesis details an experiment to measure the 25Al(d,n)26Si single proton transfer reaction, which can provide information on the astrophysically significant 25Al(p,gamma)26Si reaction. The first 3+ state in 26Si, which is predicted to dominate the stellar nucleosynthesis rate, was observed and characterized. The implications for stellar nucleosynthesis are discussed for potential stellar production sites.
