Abstract

The observation of γ rays from the decay of ⁴⁴Ti in the remnants of core-collapse supernovae (CCSNe) provides crucial information regarding the nucleosynthesis occurring in these events, as ⁴⁴Ti production is sensitive to CCSNe conditions. The final abundance of ⁴⁴Ti is also sensitive to specific nuclear input parameters, one of which is the ⁵⁷Ni(p,γ)⁵⁸Cu reaction rate. A precise rate for ⁵⁷Ni(p,γ)⁵⁸Cu is thus critical if ⁴⁴Ti production is to be an effective probe into CCSNe. To experimentally constrain the ⁵⁷Ni(p,γ)⁵⁸Cu rate, the structure properties of ⁵⁸Cu were measured via the ⁵⁸Ni(³He,t)⁵⁸Cu*(γ) reaction using GODDESS (GRETINA ORRUBA Dual Detectors for Experimental Structure Studies) at Argonne National Laboratory's ATLAS facility. Details of the experiment, ongoing analysis, and plans are presented.
