Abstract

A collision-induced-desorption (CID) phenomenon was investigated using a new combination system of molecular beam and Fourier transform infrared spectroscopy (FTIR). We observed the desorption of N₂ from the Ni(100) surface induced by collision with hyperthermal Xe atoms. The Xe atoms were accelerated up to 1.23 eV in a supersonic molecular beam by seeding in He gas. The FTIR spectra of N₂ on the Ni(100) surface were taken during the CID process. The cross section of CID depended on the incident energy of Xe. For 1.23 eV, it was 1.2 ± 0.09 Å². The relationship between binding energy of N₂ on Ni(100) surface and the threshold of incident energy of Xe for CID was discussed.
