Recently measured cross sections for inelastic $0_2^{+}$ and $3^{-}$ excitations in ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ + ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ are analyzed in the framework of coupled channel calculations. The correlation between the peaks in both channels is explained in terms of a strongly mixed resonant state of the nucleus-nucleus system. The equivalent local potentials including the channel couplings are calculated for each channel. The resonances are seen to arise in all channels simultaneously at the barrier tops of these effective potentials.
