用分子动力学的方法研究了100ev N原子轰击下凝聚态N2试样的溅射过程。所观察到的特征大体上与以前的氩溅射研究相似。时间和空间分辨的测量提供了有关溅射分子的原始位置及其能量分布的时间依赖性的新信息。相对于质心平移运动，旋转自由度和振动自由度是不足的。
By molecular dynamics, the sputtering of a condensed N2 sample due to 100 eV N atom bombardment is studied. The features observed in general parallel those of previous studies of Ar sputtering. Time- and space-resolved measurements give novel information on the original position of sputtered molecules and the time dependence of their energy distribution. Rotational and vibrational degrees of freedom are underpopulated with respect to center-of-mass translational motion.
