Application of the time-dependent local density approximation to collisionbetween a highly charged ion and an atom

We present a microscopic calculation of collision between a highly charged ion and a rare-gas atom in the time-dependent local density approximation. In the calculation, the single-electron wavefunctions are represented on a three-dimensional uniform grid in a rectangular box. Ions with eight charge s are treated as the core and the norm-conserving pseudopotential is used f or the electron-ion interaction. The calculated charge transfer cross secti ons are in fair agreement with measurements, the semi-empirical formula and the molecular classical over-barrier model.
