The (d,α) reaction has been studied with 79-MeV vector polarized deuterons on ${}_{}{}^{58}{}_{}{}^{}$,60,62,64Ni targets. Angular distributions of the differential cross section and vector analyzing power have been measured for strongly populated residual states in ${}_{}{}^{56}{}_{}{}^{}$,58,60,62Co up to an excitation energy of 5 MeV. The transferred orbital angular momenta L and total angular momenta J were determined from the characteristic shapes of the differential cross sections and vector analyzing powers yielding a number of new spin assignments. The $J^{\pi }$${=7\mathrm{}}^{+}$ stretched [(${\mathrm{Ni}}_{\mathrm{g}.\mathrm{s}.\mathrm{}}$${)}_{0+}$×(1${\mathit{f}}_{7/2}$${)}_{7,0}^{\mathrm{-}2}$] configuration states in the final nuclei were identified. Their location and their transition strength are used to test predictions from multiconfiguration shell-model calculations.
