The odd-odd 58Co nucleus has been studied with the 51V(10B, p2n) reaction at 33-MeV incident energy and the gamma-spectrometer Saci-Pererê. Excited states up to 8.0 MeV and spin up to 11+ have been observed. The results are compared to Shell Model calculations using the GXPF1 effective interaction, developed for use in the fp shell. The pif7/2-1<FONT FACE=Symbol>Än</FONT>(p3/2²f5/2¹) configuration was assigned to the yrast levels.
