The impact parameter dependence of KrL-shell vacancy production in Ar-Kr collisions has been studied for collision energies ranging from 0.97 MeV to 10 MeV by measuring Kr-L x-rays in coincidence with scattered Ar ions. The experimental results have been theoretically analyzed by assuming vacancy production in the quasimolecular 3 orbital to be the dominant primary mechanism for KrL-shell vacancy production. Model calculations have been performed for 3 excitation via 3-3-3 rotational coupling. The shape of the measured impact parameter dependence is satisfactorily reproduced if (“dynamically created”) vancancies are assumed to be initially present in both the 3 orbital and the 3 orbital. A strong dependence of the number of initial 3 and 3 vacancies on collision energy is observed.
