Zusammenfassung The ionization of a hydrogenlike heavy ion by the impact of a charged projectile under simultaneous irradiation by a short laser pulse is investigated within the nonperturbative approach, based on numerical solutions of the time-dependent Dirac equation. Emphasis is placed on the question of whether the laser- and impact-ionization channels interfere with each other and how this interference affects the ionization probability. To answer this question we perform detailed calculations for the laser-assisted collisions between hydrogenlike Pb81+ and α particles. The results of the calculations clearly indicate that for the experimentally relevant set of (collision and laser) parameters, the interference contribution can reach 10% and can be easily controlled by varying the laser frequency.
