Studies of atomic collisions are particularly suitable to study the fundamentally important few-body problem (fbp) [1,2]. The essence of the fbp is that the schrödinger equation is not analytically solvable for more than two mutually interacting particles even when the forces acting within the system under investigation are precisely known.
Until recently the theory of relativistic ion-atom collisions was basically restricted to the description of the motion of a single electron in the external field generated by the atomic nucleus and that of the ion-projectile. In the present article we review some of the very recent developments in the theory of relativistic ion-atom collisions which go beyond the single-active-electron.
