【 摘 要 】

Electron capture processes for low energy Ar9+ions colliding on argon dimer targets are investigated, focusing attention on charge sharing between the two argon atoms as a function of the molecular orientation and the impact parameter. Confrontation between experimental results and MC-COBM simulations have been investigated to provide access to atomic site sensitivity of the different fragmentation processes by measuring the angular correlation between the scattered projectile and the recoiling fragments.
