Cluster excitation and ionization in high velocity collisions:the atomic approach
Férid Mezdari1, Karine Wohrer-Béroff1, Marin Chabot2
(01/10/2004)

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.
