THE STUDY OF ANISOTROPY OF GAS-SURFACE SCATTERING USING SURFACE LIGHT-INDUCED DRIFT

摘要

Surface light-induced drift (SLID) which occurs under velocity-selective excitation due to the state-dependence of the probability of trapping or chemisorption has demonstrated its extreme sensitivity in studying the state-specificity of gas-surface interactions. In this paper we show that, contrary to an intuitive perception, SLID can be used to obtain the information on the angular dependence of the gas-surface scattering. We present the initial results and discuss the ways to study the scaling laws for the angular dependence of surface scattering by the SLID technique. [References: 33]
