N_2^+、N^+与Cu基底中α-Fe纳米颗粒相互作用的穆斯堡尔谱研究

Interaction of N_2^+ and N^+ ions with α - Fe nanoparticles in copper film studied by Mossbauer spectroscopy

利用穆斯堡尔方法研究了Ｎ２＋、Ｎ＋与 Ｃｕ基底中α－Ｆｅ纳米颗粒相互碰撞和碰撞后的热动力学过程。实验结果表明，Ｎ２＋与α－Ｆｅ纳米颗粒的相互作用存在着明显的非线性，即Ｎ２＋与α－ Ｆｅ纳米颗粒的碰撞截面，远大于 Ｎ＋与α－ Ｆｅ纳米颗粒的碰撞截面。

The interaction of N2+, N+ ions with α - Fe nanoparticles in copper film has been studied by Mossbauer spectroscopy. The results showed that there was obviously non -- liner effect in N2+ ion implantion. In the present study, the processes of thermodynamics for collision and after collision of N2 + and N + ions with α - Fe nanoparticles have also been investigated.
