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. === A Dissertation Submitted to the Department of Physics in Partial FulfiLlment of the Requirements for the Degree of Doctor of Philosophy. === Spring Semester, 2009. === March 3, 2009. === Nuclear Physics, 26Al, Al-26, 26Si, Si-26, Galactic Al-26 Distribution, Radioactive Ion Beam, Al-25, 25Al, Rapid Proton Process, rp-process, Classical Nova, Core Collapse Supernova, Nova, Supernova === Includes bibliographical references. === Ingo Wiedenhöver, Professor Directing Dissertation; Henry Fuelberg, Outside Committee Member; Alexander Volya, Committee Member; Grigory Rogachev, Committee Member; Peter Höflich, Committee Member.
