The 11B(p,3α) reaction measured in complete kinematics is used to search for broad resonances in 12C. Evidence for natural parity states around 10 MeV and 12 MeV is presented. The most likely assignment is 2+. Measurements of Dalitz distributions from the 2+ and 2- states at 16.11 MeV and 16.57 MeV are discussed.
