Abstract
The αC system is investigated in the generator coordinate method, where the nucleus is described by three α particles located on the apexes of an equilateral triangle. The wave functions are projected out on the and states. By modifying the size of the triangle, we analyze the importance of clustering effects in on bound states, and on αC phase shifts. These effects are found to be reduced when the total spin of the αC system increases. The coupling between the αC() and αC() channels also decreases when α clustering is introduced in . We obtain high-energy resonances in the αC scattering. These resonances, located between 15 and 30 MeV in the center of mass, are suggested to be Pauli resonances, analog to the well-known forbidden states in the two-cluster model.
