The decay of ⁵⁶Co to the levels of ⁵⁶Fe has been investigated using low-temperature nuclear orientation in the hyperfine magnetic field in iron. Based on the anisotropies of the γ rays, the following spin assignments are established: 4⁺ (4100.2- and 4298.0-keV levels) and 3⁺ (4119.8- and 4395.0-keV levels). Multipole mixing ratios of a number of γ transitions are reported. In addition, upper limits of the Fermi to Gamow-Teller matrix element ratios of the two 4⁺–4⁺ electron capture and β⁺ transitions to the 4100.2- and 4289.0-keV levels are obtained.
