Abstract
We describe electron transfer, excitation and ionization in many electron ion-atom collisions as a time-dependent process in a generalized ansatz by using explicit translational factors and internuclear distance-dependent optimized atomic basis functions. This description allows an automatic adaption of the basis to the energy of the electrons in the collision. As a first example we present results on one- and two-electron ionization in the two electron system p on He. (C) 2000 Elsevier Science B.V. All rights reserved.
