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 Mssbauer 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.
