测定了动能为400～600 keV 的 Xe29＋离子入射 Au 靶产生 Au 的 M-X 射线谱，获得了射线产额与离子入射动能的实验关系。从两体碰撞过程的能量与角动量守恒出发，推导出了低能 Xe29＋离子与 Au 原子碰撞过程中 Au M-X 射线产额与离子动能的理论关系。结果表明，在该能量范围内，射线产额的理论值与实验结果符合得较好。%According to the conservation of energy and angular momentum in the process of two body collision , the theoretical relations of Au M X-ray yields with kinetic energy of ion are deduced ,following the impact of low energy Xe29 + ions on Au target . Au M X-ray emission following the impact of Xe29 + ions of 400 ~ 600 keV kinetic energies on Au target has been detected , and the experimental relations of the X-ray yields with kinetic energy of ions are also obtained . The results show that the theoretical value has a good agreement with the experimental data in the energy range .
