The intermediate structures in ¹²C+ ¹⁶O inelastic scattering were investigated at energies around E_c.m. = 30 MeV in the ¹²C(2⁺)+¹⁶O(g.s.) single excitation and the ¹²C(2⁺)+¹⁶O(3^-,0₂⁺) mutual excitation channels and at E_c.m. = 22.6 MeV in the ¹²C(2⁺) + ¹⁶O(g.s.) single excitation channel. The angular distributions of the magnetic substate cross sections for the 2⁺ (4.439 MeV) state of ¹²C were measured by using the γ-ray recoil method in the center-of-mass ejectile-axis frame. It is shown that the structures at E_c.m. = 29.8 and 31.8 MeV in the ¹²C(2⁺)+¹⁶O(g.s.) channel are interpreted as resonances of J^π = 16⁺ or 17^- which decay dominantly through the aligned configurations with L = J-2. On the other hand, the structure at E_c.m. = 22.6 MeV is accounted for by assuming the overlap of two resonances having spins and parities of J^π = 12⁺ and J^π = 16⁺. In the ¹²C(2⁺)+¹⁶O(3^-,0₂⁺) channel, little oscillatory structures are observed in the m-substate angular distributions so that the resonance spins cannot be extracted.
