The reaction 12C(3He, α)11C was studied at the bombarding energies of 24.0, 29.2, 34.7 and 39.6 MeV and differential cross sections were analyzed in DWBA and CCBA. The large strength of shell-model-forbidden transition to the 5/2− state was found to be well explained by the multi-step processes including inelastic channels.
