【 摘 要 】

For description of ion-atom collisions the final elements approach is applied in regions close to the nuclei and in the quantum trajectory method is applied in the outer region. Applicability of the quasi-classics at the boundary provide a possibility to join two solutions. The method is computationally efficient and also provides detailed insight into the phenomenon.
