Collision cascades induced by low energy clusters impacting on metallic thin films ( I) high energy recoil atoms 低能原子簇轰击金属薄膜引起的级联碰撞(Ⅰ)高能反冲原子
C-elastic recoil detection analysis ( C-ERDA) spectrum shows that the concentration of helium atoms in He-charged Al films is about 7%. 经碳原子弹性前冲散射分析(C-ERDA),薄膜中氦原子浓度可达约7%,且分布均匀。
The multiple hits and the collisions between moving atoms make the recoil energies of target atoms increase. 原子簇轰击后的多次碰撞及运动原子间的碰撞增加了靶原子的反冲能。
