【摘要】 采用分子动力学方法研究了粒子在金属衬底上的俘获过程。发现粒子垂直入射时 ,俘获概率随入射能量的增加而减小 ,而 4 5°入射时 ,俘获概率表现出非单调行为 ,这些结果与实验观察相一致。同时还研究了俘获概率对入射角的依赖更多还原

【Abstract】 It studies the trapping process of hyperthermal particles impacted on metal substrate by molecular dynamics simulations.Results show that,for normal incidence,the trapping probability decreases with increasing of the incident energy,while for 45° incidence,the trapping probability displays a non monotonic behavior as observed in the recent experiment.The dependence of the trapping probability on the incident angle has also been investigated.更多还原
