S. %A Udías Moinelo, José Manuel %T Properties of low-lying states in Co-65 from lifetime measurements %D 2019 %@ 2469-9985 %U https://hdl.handle.net/20.500.14352/13412 %X The low-energy structure of Co-65 was studied by means of gamma(-) and fast-timing spectroscopy at the ISOLDE/CERN facility. The known level scheme of Co-65 populated following the beta(-) decay of Fe-65 was expanded. The experimental results were compared with large-scale shell-model calculations. The measured long lifetime of the (1/2(1)(-)) level confirms its nature as a highly collective state with proton excitations across the Z = 28 gap and neutrons across the N = 40 subshell. %~
