| Résumé : |
|
The independent atom and electron model [1] is introduced in a quantum context and associated approximations tentatively estimated. Confrontation of the model to measured ionization and excitation cross sections of small ionic carbon clusters Cn+ in collisions with helium at an impact velocity of 2.6 a.u is presented. |
