摘要：

Multiple electron capture by highly charged ions in collision with rare gas targets is experimentally investigated. Differential cross sections are measured for specific processes in which both the number of electrons lost by the target and captured by the projectile are determined. This set of data is compared with the predictions of the molecular Coulombic barrier model. The good predictive quality of this model is confirmed but deficiencies are pinpointed which are attributed to the neglect of 'simultaneous' electron transfers as well as to the intrinsic static character of the model.
