Mirror symmetry in the f7/2 shell below 56Ni, excited states and electromagnetic transition rates in 55Ni and 55Co

Mirror nuclei near doubly magic ⁵⁶Ni are being explored at TRIUMF, Canada's particle accelerator center. A stable ²⁰Ne beam experiment to produce ⁵⁵Co and a complimentary radioactive ²¹Na beam experiment to produce ⁵⁵Ni were conducted. These experiments leveraged TIGRESS for γ rays, SFU's TIP CsI Ball for charged particles, specialized Ca targetry, and Doppler-shift lifetime methods. Additionally, the ⁵⁵Ni experiment used EMMA for enhanced selectivity. These experiments aim to identify the energies, spins, and parities of excited states in ⁵⁵Ni, establish mirror energy differences between ⁵⁵Ni and ⁵⁵Co, compare the excitation of reaction products at different beam energies (50, 55, 60 MeV) for ⁵⁵Co, measure the temperature of ⁶⁰Zn and ⁶¹Ga compound nuclei, measure EM transition rates for the states in ⁵⁵Ni and ⁵⁵Co, and provide reliable data for shell model calculations for hole states in the $f_{7/2}$ nuclear orbital near ⁵⁶Ni. This proceeding reviews the methodology behind and current state of the ⁵⁵Co experiment analysis with preliminary results.
