The structures of the neutron-rich $^{69,71,73}\mathrm{Co}$ isotopes were investigated via $(p,2p)$ knockout reactions at Radioactive Isotope Beam Factory, RIKEN. Isotopes interest studied using DALI2 $\ensuremath{\gamma}$-ray detector array combined with MINOS target and tracker system. Level schemes reconstructed $\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ coincidence technique, tentative spin-parity assignments based on measured inclusive exclusive cross sections. Comparison shell-model calculations Lenzi-Nowacki-Poves-Sieja LNPS PFSDG-U interactions suggests coexistence spherical deformed shapes low excitation energies in isotopes. distorted-wave impulse approximation (DWIA) framework was used to calculate single-particle These values compared experimental findings.
