Excitation functions for 18O + α elastic scattering were measured by a method using inverse kinematics and a thick gas target. An analysis of the data corresponding to the excitation energy regions of 11.8-13.7 MeV and 19.0-22.0 MeV in 22Ne was carried out. A surprising splitting of 1-, 3-, 7-, and 9- α-cluster levels into doublets was found in 22Ne.
