We investigated decay properties of the broad resonance around 10 MeV in ¹²C and measured inelastic scattering of 386 MeV α particles on ¹⁶O at extremely forward angles including 0°. We have found that the lower component of the broad 0⁺ resonance at 10 MeV in ¹²C decayed to the ⁸Be + α channel, and that the higher component decayed both to the ⁸Be + α channel and to the ⁸Be(2+) + α channel. On the ¹⁶O nucleus, we have found two 0⁺ resonances at 16.7 MeV and 18.8 MeV, which are near the 4α breakup threshold. On the analogy to the broad resonances near the 3α threshold in ¹²C, they are considered to have the ¹²C(0⁺2) + α cluster and the ⁸Be + ⁸Be cluster structures, respectively. It is consistent with the result of the experiment for the ¹²C(⁴He,⁸Be)⁸Be and ¹²C(⁴He,¹²C∗ → ⁸Be + α)α reactions.
