| Résumé : | Motivated by interpretations of a broad structure at 32.5 MeV in the 12C(12C, 12C(02+)) 12C(02+) doubly inelastic scattering cross sections in terms of linear chains of α particles, we study in a microscopic model with an exact account of antisymmetrization the time evolution of a system of two α clusters. The evolution of the system is obtained from a time-dependent variational principle and visualized with matter densities. Even in the most favourable case, an initial two-cluster structure completely disappears in less than 2 × 10-22 s. This result casts doubts on the observability of longer α chains. |
