ORAL
Abstract
The 57Ni(p,γ)58Cu reaction rate significantly impacts nucleosynthesis in a variety of astrophysical sites. In core-collapse supernovae this reaction impacts the production of observable isotopes 44Ti and 59Ni. Furthermore, the 57Ni(p,γ)58Cu reaction rate significantly impacts 57Fe production via the 𝜈p-process in multiple astrophysical environments. Despite its importance, no experimental rate exists for this reaction. To experimentally constrain this rate, structure properties of 58Cu were measured via the 58Ni(3He,t)58Cu reaction using both GODDESS (GRETINA ORRUBA Dual Detectors for Experimental Structure Studies) at Argonne National Laboratory’s ATLAS facility and the Enge split-pole spectrograph at the University of Notre Dame’s Nuclear Science Laboratory. These measurements focused on precisely determining the level energies of 58Cu. Additionally, these measurements may provide complementary structure information that impacts the reaction rate, such as level spin, proton branching ratios, and gamma branching ratios. Experimental procedures and preliminary analysis will be presented.
