摘　　要：在重离子与靶原子直接碰撞导致原子内壳层空穴产额与离子入射动能关系的基础上,计算了单离子入射引起的原子间碰撞产生的原子内壳层空穴产额。给出了低能重离子与靶原子碰撞过程,原子内壳层X射线单离子产额与离子动能的关系。较好地解释了动能300~600 ke V的Xe^27＋离子入射Mo靶,激发的Mo的L X射线的实验结果。According to the theoretical relationship of atomic inner shell holes yields with kinetic energy of ions, by heavy ion collisions with atom directly, we calculated the inner shell holes yields by the collision between atoms for the single ion incident. We deduce the theoretical relationship of atomic inner shell X-ray yields with kinetic energy of ions by the low energy heavy ion collision with target atoms. The experimental results of Mo L X-ray radiation by Xe^27＋ions of 300-600 ke V kinetic energy incident Mo target is interpreted.
