SHIM 2015 Swift Heavy Ions in Matter

All atoms and molecules can – even in their ground state – form clusters, weakly bound molecules, held together by the van der Waals force. The smallest if this type is the dimmer, composed of two atoms/molecules. While the Ne dimer is a representative for rare gas dimers in general, the He dimer is a quite exotic object, with a broad internuclear distribution, stretching up to several 100 a....

Non-equilibrium and equilibrium charge state distributions for 2.0 MeV/u Sq+ (q = 6−16) and Cq+ (q = 2−6) ions after penetrating carbon foils have been investigated experimentally. Those wide ranges of the initial charge states have proved that charge state distributions, mean charge states, and distribution widths for projectile ions without K-shell holes, Sq+ (q = 6−14) and Cq+ (q = 2−4),...

Fast Highly Charged Ions (HCIs) going through matter induce material modifications and, in turn, their stopping power, charge state and excited states are affected by the material encountered. Here, we report on experimental studies, performed at GANIL, on the production and transport of HCIs excited states in thin solid targets in the so-called high velocity domain. Solids of various...

Since the prediction of the Interatomic Coulombic Decay (ICD) by Cederbaum et al. in 1997 [1], the rare gas atomic dimers have been widely investigated by photon impact. However, the investigation of dimers with the ions and electrons as the projectile is still scare [2-6]. For neon dimer, only a few works involved with heavy ions were reported [4]. Utilizing the reaction microscope [7], we...
