A NEW APPROACH TO ELECTRON TRANSLATION IN LOW ENERGY ATOMIC COLLISIONS A.\ K.\ Belyaev$^{\bullet}$, D.\ Egorova$^{\star}$, J.\ Grosser$^{\star}$, T.\ Menzel$^{\star}$ $^{\star}$ Institut f"ur Atom- und Molek"ulphysik, Universit"at Hannover, Germany \\ $^{\bullet}$Department of Theoretical Physics, Pedagogical University of Russia, St.\ Petersburg, Russia \\ We consider a conceptional problem that arises in the quantum-mechanical calculation of inelastic atomic collisions: Nonzero coupling matrix elements seem to cause inelastic transitions at arbitrary large internuclear distances. A standard remedy, the use of electron translation factors, is not applicable in full quantum calculations. We present a new procedure, which allows to deal with the problem in the framework of a full quantum approach.
