This project involves the surrogate analysis of data taken with Hyperion, a particle-γ coincidence detector array utilizing in-beam γ-ray spectroscopy. The reactions measured were 64,70Zn(p,d) and 64,70Zn(p,t) as surrogates for 61,62,67,68Zn(n,γ). The experiment was performed in fall 2021 at Texas A&M University’s Cyclotron Institute with a 27-MeV proton beam from the K150 cyclotron. Preliminary results presented are the extracted γ-decay probabilities; further analysis is under way using these results in constraining (n,γ) cross sections.
