Abstract A spectroscopic study is performed for high spin states of55Fe,55Co and57Ni. To populate the investigated residues with a relevant cross section, the fusion evaporation reactions of30Si(28Si, 2pn)55Fe,30Si(28Si, 2np)55Co and4He(54Fe,n)57Ni were chosen. To identify the newγ transitions and to build the energy level schemes,γ — γ coincidence techniques together with excitation functions were employed. Angular distributions andγ — γ angular correlations allowed us to assign the spin values of the nuclear states. The previous level scheme of55Fe is extended into the region between 6.5–11 MeV of excitation energy, up to spin 27/2, while the yrast decay paths of57Ni and55Co are reported here for the first time. Experimental data are fairly well reproduced by Glaudemans' shell model calculations.
