氘气分子在Ag(111)上的吸附-脱附

The Absorption and Desorption of Deuterium Gas Molecular on Ag(111)

气体分子在金属表面上的解离吸附能垒值是一个非常重要的动力学参数.通过研究脱附分子的角分布和动能分布来了解吸附能垒的信息,是获得解离吸附能垒的一种有效的方法.通过用一个计算脱附分子角分布和动能分布的新模型.研究实验测量的从银单晶表面Ag(111)脱附的氘分子(D2)的动能分布.

A value of energy barrlers to dissociative adsorption on an Ag （111） single crystal surface is a very important dynamical parameter. To obtain the information of energy barriers of dissociative absorption by way of studying angle distribution and energy distribution of desorptive molecular is the effective way. This paper has, through narrating a new model of calculating angle distribution and energy distribution of desorptive molecular, made a study of the energy distribution of dissociative deuterium gas molecular on silver single crystal surface.
