Abstract
EXAFS measurements were made on Ni-fine particles (14–5 nm in size) prepared by the gas evaporation technique. Data were analysed by the fine adjustment method developed by Teo et al. Substantial lattice relaxation shows an increase in the nearest Ni-Ni bond distance (R 1), a decrease in the coordination number (N1) and an increase in the Debye-Waller factor (σ1). These facts can be explained as a result of the chemisorption of oxygen on the surface of fine particles.Keywords
