Abstract
We present a new scheme to solve the time dependent Dirac-Fock-Slater equation (TDDFS) for heavy many electron ion-atom collision systems. U p to now time independent self consistent molecular orbitals have been used to expand the time dependent wavefunction and rather complicated potential coupling matrix elements have been neglected. Our idea is t o minimize the potential coupling by using the time dependent electron ic density to generate molecular basis functions. We present the first results for 16 MeV S16+ on Ar.
