| Résumé : | Local αα potentials reproducing the αα phase shifts fail to describe 12C as a 3α system. Nonlocal αα potentials that renormalize the energy-dependent kernel of the resonating group method allow interpreting simultaneously the ground state and 0+2 resonance of 12C as 3α states. A comparison with fully microscopic calculations provides a measure of the importance of three-cluster exchanges in those states. © 2007 Elsevier B.V. All rights reserved. |
