Infrared spectroscopic study of radiation-induced adsorption of n-hexane on a beryllium surface

摘要

Radiation-stimulated adsorption on a beryllium surface is studied by IR reflection-absorption spectroscopy. It is found that gamma-irradiation at room temperature leads to the appearance of n-hexane adsorption centers on a beryllium surface according to molecular and dissociation mechanisms. The kinetics of n-hexane adsorption in a D'D mu-n-hexane system is studied; activated dissociative chemisorption accompanied by formation of beryllium alkyls and surface hydrides is observed at absorbed doses 15 kGy ae D(gamma) ae 35 kGy. A possible mechanism of this process is suggested.
