Measurement of low-lying proton resonances in ²⁶Si using the ²⁵Al(d,n)²⁶Si proton transfer reaction.

The synthesis of galactic ²⁶Al is an interesting subject that spans from nuclear astrophysics to observational astronomy. This isotope is observed through γ-ray astronomy and is a probe into the ongoing nucleosynthesis in the galaxy as well as the frequency of Core-Collapse Supernovae. One of the reactions of interest for the ²⁶Al yield is ²⁵Al(p,γ)²⁶Si, which bypasses the population of the ²⁶Al ground state. An experiment using the proton transfer reaction ²⁵Al(d,n)²⁶Si was performed with the RESOLUT radioactive beam facility at Florida State University to study proton resonances just above the separation energy. As a result, the proton resonance spectrum and cross sections were obtained with better precision than in previous measurements. Further results and astrophysical implications will be discussed.
