我们观测到了Pt（111）表面散射的速度和角分布，实验上将散射过程分为直接非弹性通道和捕获-解吸通道。捕获-解吸通道导致麦克斯韦速度分布在表面温度和一个cos θ角的依赖性，而直接的非弹性通道表现出的出口动能和入射动能和表面温度之间的线性关系。
Velocity and angular distributions for Xe scattered from clean Pt (111) have been observed which permit the scattering process to be experimentally divided into a direct inelastic channel and a trapping-desorption channel. The trapping-desorption channel leads to Maxwellian velocity distributions at the surface temperature and a cos θ angular dependence, while the direct inelastic channel exhibits a linear relationship between exit kinetic energy and both incident kinetic energy and surface temperature.
