Abstract
Due to the quality of a large number of results obtained with the CTMC, method for collisions involving H and He targets, it is obviously tempting to extend the method to multielectronic targets. The simplest target to use seems to be Li, which has two electrons in the 1s orbital and a less bound electron on the 2s shell. Then, the method is extended to multielectronic targets such as Ne or Ar.

Notes
- 1.
The electron loss process definition depends onto the authors. Here, it characterizes the ionization of the projectile, while in most cases it means charge changing.
- 2.
The ED model is not detailed here for reasons of clarity. For more details see [16].
