摘要

在二元碰撞模型中，对快原子束和快离子束对金属靶的作用进行了对比分析。在主敲原子谱和辐射缺陷形成的效率和机制方面，快原子辐照已被证明更接近于核反应堆中的中子辐射。结果表明，在能量为0.2 ~ 0.3 MeV的快速碳原子辐照下，一个原子位移级联的平均辐射缺陷数比同等能量离子的SRIM程序计算值高出4 ~ 5倍。结果表明，在穿透过程中，能量小于0.4 MeV的原子电离的概率可以忽略不计。

Comparison of Influence of the Fast Atom Beam and Ion Beam on the Metal Target

A comparative analysis of a fast atom beam and ion beam effect on a metal target in the binary collision model is performed. Irradiation by fast atoms has been shown to more closely correspond to neutron radiation in a nuclear reactor, in terms of the primary knocked-on atom spectrum and the efficiency and mechanism of the radiation defect formation. It was found that upon irradiation by fast carbon atoms with an energy of 0.2-0.3 MeV, the average number of radiation defects in the displacement cascade of one atom is four to five times higher than the calculated values using the SRIM program for ions with the same energy. It is shown that during penetration in the target, the probability of ionization of atoms with energies less than 0.4 MeV is negligible.

期刊介绍： Laser and Particle Beams is an international journal which deals with basic physics issues of intense laser and particle beams, and the interaction of these beams with matter. Research on pulse power technology associated with beam generation is also of strong interest. Subjects covered include the physics of high energy densities; non-LTE phenomena; hot dense matter and related atomic, plasma and hydrodynamic physics and astrophysics; intense sources of coherent radiation; high current particle accelerators; beam-wave interaction; and pulsed power technology.
