我们给出了一个排列分辨的散射实验，表明入射同核双原子分子的排列对散射分子的角分布、碰撞过程中的能量损失和俘获几率有很大的影响。在LiF(001)面沿[110]方向垂直于散射面的方向散射时，观察到明显的表面彩虹散射。结果可以根据入射分子感受到的表面波纹的排列相关性来理解。在高度定向的热解石墨表面上捕获端面碰撞的几率较高，这一事实与观察到的这种几何形状的较大能量损失有关。
We present an alignment-resolvedscattering experiment showing that the alignment of an incident homonuclear diatomic molecule strongly influences the angular distribution of scattered molecule, the energy loss during the collision, and the trapping probability. Clear surface rainbow scattering has been observed on LiF(001) whenis scattered along the [110] azimuth with its axis perpendicular to the scattering plane. The results can be understood based on the alignment dependence of the surface corrugation felt by an incident molecule. The fact thattrapping probability on a highly oriented pyrolytic graphite surface is higher for end-on collision has been associated with the observed larger energy loss for this geometry.
